Measuring

This is a difference most Americans are aware of: most countries use the metric system rather than U.S. customary units, and most use Celsius instead of Fahrenheit. Countries such as the UK and Canada still use some imperial units in everyday life, but they mainly use the metric system. Another measure that confuses foreigners is the particular way ingredients are measured in American recipes, which often use cups, tablespoons, and teaspoons rather than measurements by weight.

Fun fact: The only other countries that use the Imperial system officially are Liberia and Myanmar.

Sales tax

Do you find having to calculate sales taxes annoying? That’s a unique American experience. In the majority of the world, the price you see is the price you pay , because it has the sales tax already added.

Why is it different in America? Sales taxes vary across states , so retailers find it easier to showcase the base price and then calculate the total at checkout.

Cutlery use

Many Americans abroad are surprised by the realization that not everyone uses a knife and fork in the same way they do . In fact, no one else does. While most Americans have learned the American style —also called the zig-zag or fork switching method— that involves using the fork in the left hand for cutting and then changing it to the right to pick up the food, European and Latin American countries don’t do this . It might seem like a small difference, but it completely changes the way you eat.

4

Iced drinks

Do other countries not have ice? They do, but they don’t necessarily assume everyone will want it. While serving water and other beverages with ice is customary in America, in many other countries, you need to request it —even during the hottest of summers.

But even if you get ice, many times you will need to specify the amount : the same drink that would be filled with ice cubes in America might come to you with just two or three cubes elsewhere.

Date formatting

The U.S. is not completely alone on this one, but there’s a difference big enough to be worth mentioning. The standardized way of recording the date in America is month-day-year , a convention also followed by some Caribbean and Asian countries. But in the rest of the Western world, the conventional format is day-month-year , which can lead to confusion for Americans. In most Asian countries , the most commonly used format is year-month-day .

The word ‘American’

In the English language, ‘American’ is the only way to refer to people with U.S. citizenship . Other words, such as ‘Usian’ or ‘Unitedstatian’ have been proposed, but never stuck. This is why many Americans are surprised when other countries —Latin American countries in particular— use ‘American’ for anyone in the American continent , or continents, another big difference. In most European and Latin American countries, there is a different word for U.S. citizens, such as the Spanish ‘estadounidense’ or the Portuguese ‘estadunidense’ .

Moving out at 18 years old

This one is not so black and white, but more like a general tendency. Compared with most of Europe, Latin America, and Asia, Americans give serious consideration to the possibility of moving out after high school. Not everyone does, and not everyone can afford it, but it's fairly common.

In other countries, young adults generally move out if their job or education requires it , but they tend to stay at home a few more years if they can.

8

Driving a car as a teenager

America is quite car-centric , especially if you live outside of the big cities. While not everyone can afford to have a personal car —even a second-hand one—, it is common for 16 and 17-year-olds to legally drive their parents’ car, or save for their own.

In the rest of the world, the chances of high schoolers driving themselves to school are much lower, as most countries don’t allow underage kids to get a driving license .

9

Solo cups

Do plastic cups exist outside of the U.S.? They do, but they are not as iconic or as widely used as Solo cups, introduced in the 1970s as a disposable but sturdy cup for parties and events. Many foreigners visiting America are surprised when they realize that solo cups are a real thing , and not something that just happens in movies.

10

Filing taxes

Taxes in the U.S. are not that different from taxes in other countries, except for how they are filed . During tax filing season, thousands of Americans direct their efforts to ensure they have properly reported their income and that their return will match the IRS’s data.

In other parts of the world, however, the one responsible for calculating and filing taxes is the government , while citizens merely corroborate that everything is in order.

The Cardiff Giant

In 1869, workers digging a well in Cardiff, New York, uncovered what appeared to be a 10-foot-tall petrified man. Locals rushed to see the "giant," paying admission to witness history in the soil.

But, as it turned out, it wasn’t ancient at all. A man named George Hull had buried the statue as a prank and made some quick money from the curious crowd.

2

War of the Worlds Broadcast

This very famous hoax took place on the eve of Halloween 1938. Orson Welles’s radio adaptation of The War of the Worlds aired as if it were breaking news . Many listeners tuning in late thought Martians had really landed in New Jersey.

Some packed up their cars or called the police in panic. Though no invasion occurred, the broadcast became a legend in media history.

3

The Balloon Boy

In 2009, Americans watched live TV coverage of a silver balloon drifting across the skies of Colorado , fearing that a six-year-old boy was trapped inside . The story gripped the nation for hours.

When the balloon finally landed empty, police discovered the child hiding safely at home. His parents later admitted it was a publicity stunt gone wrong.

4

The Feejee Mermaid

In 1842, showman P. T. Barnum unveiled a marvel: a preserved "mermaid" supposedly from the South Seas . Crowds lined up to see the half-fish, half-woman curiosity.

The truth was stranger still. It was the upper body of a monkey sewn onto a fish tail and covered in papier-mâché.

5

The Great Moon Hoax

Readers of The New York Sun in 1835 were astonished by reports claiming that scientists had spotted bat-like people and crystal palaces on the Moon through a powerful new telescope.

The story was pure invention, but circulation went up. By the time the truth came out, the paper’s readership had reportedly increased dramatically.

6

The Crop Circles Craze

When perfect circles began appearing overnight in wheat fields , people talked about UFO landings. The shapes seemed too precise to have been made by human hands.

But, in 1991, two Englishmen confessed they’d used boards and ropes to flatten the crops. While this revelation explained many of the formations, the mystery lives on in popular imagination.

7

Alien Autopsy Film

In 1995, a grainy black-and-white video surfaced, showing doctors dissecting what seemed to be an alien recovered from the 1947 Roswell crash. The footage spread quickly worldwide.

Years later, the filmmaker admitted that the film was staged, using latex models and fake organs.

The Manti Te’o girlfriend hoax

Notre Dame football star Manti Te’o captured hearts when he revealed that his girlfriend had died of leukemia . Sports fans wept over the tragic love story.

But reporters later learned that the woman never existed. It was an elaborate online catfishing scheme.

9

The Patterson–Gimlin Bigfoot film

In 1967, a short film shot in California showed a large, hairy creature striding through the woods . Many viewers thought this was real proof of Bigfoot´s existence.

Decades later, one participant claimed it was a man in a gorilla suit, but that claim failed to convince many people who prefer to believe in the existence of this creature.

10

The Drake’s Plate of Brass

In 1936, a shiny brass plate found in California seemed to confirm that explorer Sir Francis Drake had landed there in 1579. Historians called it a priceless relic.

For decades, the plate was displayed proudly, until metallurgical tests in 1977 proved it was modern . It had been made as a practical joke among historians that went too far.

11

Paul Is Dead

The final entry on our list might not be American per se, but it drew much attention on these shores. In 1969, rumors spread that Beatle Paul McCartney had died and been secretly replaced by a double . Fans scoured album covers for "clues" like hidden messages and backward songs.

Paul, very much alive, later joked about it. The bizarre theory became a lasting pop-culture phenomenon.

A rivalry becomes a business success

During the Great Depression, Harland Sanders ran a humble Shell station in Corbin, Kentucky. Back then, business was cutthroat, and Sanders found himself in a bitter feud with Matt Stewart, a rival gas station owner who kept painting over Sanders’ highway signs to redirect traffic. After several warnings went unheard, Sanders marched over to confront Stewart.

When Stewart was caught in the act, a physical confrontation quickly escalated. Stewart drew a pistol and shot a Shell manager who was accompanying Sanders, killing him on the spot. Sanders retaliated by firing back and wounding Stewart, who was later arrested and sentenced to prison for murder. With his main competitor safely behind bars, Sanders was able to expand his service station, perfect his pressure-frying method, and ultimately transform his business into a massive commercial success.

The KFC you know today exists thanks to Wendy’s

Although you may view KFC and Wendy’s as distinct competitors, the reality is that the chicken giant owes its structural identity to Dave Thomas, the founder of Wendy’s. In the 1960s, Thomas worked as a head chef and regional manager for the Colonel’s franchises.

He was a marketing whiz who personally convinced Colonel Sanders to star in his own television commercials, cementing his status as a living mascot. Furthermore, Thomas created the iconic red and white striped bucket design. He became so wealthy from his shares and success at KFC that he used his payout to establish his own burger empire, Wendy’s, in 1969.

The secret recipe's security

The legendary blend of "11 herbs and spices" is one of the most famously guarded secrets. Did you know KFC keeps the recipe locked inside a top-secret vault at the corporate headquarters in Louisville, Kentucky?

The vault, encased in thick layers of concrete, is protected by motion sensors, security cameras, and 24/7 guards. To ensure the formula is never leaked, KFC splits the production pipeline: two different companies are hired to mix separate halves of the spice blend. Neither company knows the other's ingredients, and a computer system automatically combines the two halves before the seasoning is shipped out to individual franchises.

KFC for Christmas in Japan

In the United States, a Christmas dinner consists of roasted turkey or ham. In Japan, however, Nativity food comes in a cardboard bucket. This wild tradition dates back to 1974, sparked by Takeshi Okawara, the manager of the country's first KFC branch.

After overhearing homesick Western expats lamenting how difficult it was to source a holiday turkey in Japan, Okawara launched the national "Kentucky for Christmas" campaign, which exploded into a cultural phenomenon. Today, an estimated 3.6 million Japanese families celebrate Christmas Eve with KFC, with patrons placing their orders months in advance to avoid long lines.

Colonel Sanders hated KFC

By 1964, 73-year-old Colonel Snaders felt he was no longer cut out for the pace of corporate life. He sold the Kentucky Fried Chicken company to a group of investors for $2 million, under a contract that allowed the brand to continue using his likeness.

As executives changed the original recipes to cut costs, Sanders grew to hate the food KFC was serving. He began travelling the country, showing up unannounced at franchises to taste the food, throw public tantrums, and openly tell the media that the new gravy tasted like "wallpaper paste" or "sludge". He even attempted to open a rival restaurant and sued KFC for using his image, leading the company to counter-sue him. Eventually, KFC paid him an additional million dollars just to stop making public scenes.

6

KFC Double Down

KFC has never been afraid of pushing nutritional boundaries, but in 2010 they certainly hit another level. The Double Down features bacon, Monterey Jack cheese, and a Colonel's special sauce encased between two seasoned, crispy slabs of fried chicken breast instead of bread buns.

The item sparked a media frenzy, with health advocates calling it a dietary disaster and foodies treating it as a dare. Ultimately, it proved to be a commercial hit. As it turns out, when it comes to extreme fast food, consumers are more than willing to ignore the carbs in favor of deliciousness.

7

That time KFC ran out of chicken

A fried chicken restaurant running out of its main ingredient sounds like a nightmare, but in 2018, it became real for KFC in the United Kingdom. In an effort to optimize logistics and save money, management switched its delivery contract to DHL. The transition went completely wrong, resulting in a supply chain jam that left over 900 UK locations with no chicken to fry.

Hundreds of stores were forced to shut down temporarily, sparking nationwide outrage, with desperate citizens even calling the police to complain. KFC managed to restore its reputation by leaning into self-deprecating humor, purchasing newspaper advertisements that featured an empty bucket rearranged to read "FCK".

The problem with the slogan in Chinese

When international fast food brands began expanding into foreign territories in the late 1980s, errors were very common. KFC experienced this firsthand when it opened its first store in Beijing, China, in 1987. The company wanted to proudly display its world-famous catchphrase, "Finger-Lickin' Good", to tempt local diners.

Unfortunately, due to an oversight in Mandarin translation, the slogan was literally translated to "Eat Your Fingers Off". While the phrase initially startled and amused local consumers, the brand quickly corrected the translation mishap to something more culturally appropriate and appetizing.

9

KFC's video game

Decades after the Colonel’s passing, KFC’s marketing division decided to lean into modern internet subcultures. In 2019, the brand shocked the gaming community by releasing an official, anime-style video game titled I Love You, Colonel Sanders! A Finger Lickin’ Good Dating Simulator.

Developed as a visual novel, the free game places the player in a culinary school alongside a young and handsome romanticized version of Colonel Sanders. The goal of the game is to successfully navigate cooking school battles while attempting to woo the chicken chef. Against all odds, the game became a viral sensation.

KFC releases its own console

Following the unexpected success of their video game, KFC’s marketing team announced the KFConsole in 2020. Many assumed it was an April Fool’s joke, but it turned out to be a genuine gaming PC.

The most bizarre feature of the console is its custom "Chicken Chamber". This specialized compartment uses the heat generated by the computer’s internal components to keep pieces of fried chicken warm and crispy while you play video games.
