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 .

6

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.

Potato chips

Back in 1853, a cranky diner in Saratoga Springs, New York, complained that his fries were too thick . Irritated, Chef George Crum sliced them paper-thin and fried them crisp to prove a point . To everyone’s surprise, the customer loved them.

What began as a moment of frustration turned into America’s favorite salty snack, inspiring an entire industry of chips and flavors.

2

Popsicles

In 1905, 11-year-old San Francisco native Frank Epperson accidentally left a cup of soda powder and water outside overnight, with a stick still in it. The next morning, it had frozen solid in the chilly air .

Epperson dubbed it the "Epsicle," which was later renamed the Popsicle. That childhood experiment became one of the most enduring summer treats.

3

Chocolate chip cookies

Ruth Wakefield ran out of baker’s chocolate when she was making traditional chocolate cookies at her Massachusetts inn, the Toll House, in the 1930s. She chopped up Nestlé chocolate snack bars instead . She expected them to melt evenly into the dough, but they stayed in chunks.

The warm, gooey results became an instant hit with her guests. Nestlé soon partnered with her to print the recipe on chocolate bar wrappers, and the rest is history!

4

Corn flakes

In 1898, the Kellogg brothers accidentally left cooked wheat, unprocessed wheat kernels simmered until tender, sitting out overnight at their Michigan sanitarium, where they promoted a healthy living based on vegetarianism, exercise, sunlight, and strict hygiene. By morning, it had gone stale, but when they rolled and baked it, the flakes came out crisp and tasty .

That happy mistake inspired a new breakfast idea: simple, wholesome, and ready to pour.

5

Coca-Cola

In one of the most profitable blunders of all time, Atlanta pharmacist John Pemberton was mixing a headache tonic in 1886 when he mistakenly blended his syrup with carbonated water instead of plain water .

Finding the result quite tasty, Pemberton opened a local soda fountain and found immediate success.

6

Cheeseburgers

In the 1920s, a teenage cook in Pasadena accidentally dropped a slice of cheese onto a sizzling hamburger . Instead of tossing it out, he served it to the customer.

The melted topping added a rich, savory twist that caught on fast. Soon, diners across America began adding cheese to burgers, helping to spread this classic.

7

Hard pretzels

One Pennsylvania baker in the 1800s left his soft pretzels in the oven too long, burning them to a deep brown . Expecting a disaster, he tried one and loved the unexpected crunch.

That overbaked batch became the first hard pretzel. The crispy, salty snack soon gained fans nationwide.

8

Slurpees

In the 1950s, a Kansas soda shop’s cooler broke down, freezing its drinks halfway . Instead of throwing them out, the owner sold the icy concoctions to curious customers.

They loved the slushy texture so much that he built a machine to reproduce it. The Icee — and later the Slurpee — turned an equipment failure into an omnipresent machine at every 7-Eleven.

9

Tortilla chips

In 1940s Los Angeles, a tortilla factory ended up with piles of leftover tortillas. Rather than waste them, workers cut them into triangles and fried them up .

The crunchy bites were a surprise hit. What started as a practical way to use scraps soon became a nationwide snack.

10

Tootsie Rolls

Crafty candy maker Leo Hirschfeld wanted to stretch his chocolate supply in 1896, so he experimented by blending in other ingredients such as sugar, corn syrup, and condensed skim milk . The texture turned chewy instead of smooth, but the flavor was rich and lasting.

He named it after his daughter’s nickname, "Tootsie." His thrift-born invention became a candy classic.

11

Reese’s Peanut Butter Cups

Back in 1928, a former Hershey employee, H.B. Reese, was tinkering with leftover chocolate at home when he combined it with sweetened peanut butter . The unexpected pairing turned out to be a great-tasting treat.

His homemade experiment evolved into a small business, and later became a candy legend when Hershey acquired the brand.

12

Fudge

According to the popular story, a batch of caramel didn’t heat properly one night , and the cook sighed that it had been "fudged." The softer texture, however, turned out wonderfully creamy.

That tasty error spread quickly through American kitchens and college towns, becoming the classic dessert that it is today.

1

Jackson, Mississippi

Did you know Jackson, Mississippi, is named after the 7th U.S. President, Andrew Jackson? It is one of the four state capitals named after American presidents —the other three are Jefferson City (Missouri), Lincoln (Nebraska), and Madison (Wisconsin).

Jackson is the only U.S. capital built on top of an extinct volcano. Interestingly, during the Civil War, the city was burned by Union troops, giving it the nickname "Chimneyville". In addition, Jackson is best known for being the center of the civil rights movement during the 1950s and 1960s.

2

Santa Fe, New Mexico

Founded by Spanish colonists in 1610 as the capital of the colony of New Mexico, Santa Fe is the oldest U.S. city that still functions as a state capital today.

But that's not the only peculiarity of this quaint city with a temperate climate and a unique historical and cultural richness. At 7,000 feet above sea level, Santa Fe is also the highest U.S. capital.

3

Honolulu, Hawaii

Known for its spectacular beaches and rich cultural heritage, Honolulu is the only state capital not on the North American mainland. Considered the birthplace of modern surfing, it also has the highest average annual temperature of any U.S. state capital.

But those aren't the only interesting facts about Hawaii's capital. Here are a few equally (or more) crazy ones: it hosts the only royal palace in the United States (Iolani Palace), the island is made up of volcanic soil, and it houses the world's largest open-air shopping mall (Ala Moana Center).

4

Annapolis, Maryland

Annapolis is a historic city on the shores of the Chesapeake Bay, known for its colonial architecture, nautical tradition, and academic value. But did you know it is also the smallest U.S. capital by land area? Just 6.7 square miles!

Annapolis was also one of the nine capitals the United States has had throughout its history. For nine months during the Revolutionary War, Maryland's current state capital served as the seat of the Confederation Congress.

5

Bismarck, North Dakota

If you thought Juneau, Alaska, had the lowest average winter temperature of all state capitals, think again! It's actually Bismarck, North Dakota, where the coldest temperature ever recorded was -45°F. Imagine that!

Bismarck was founded in 1872 on the banks of the Missouri River. The city was named after Otto von Bismarck, the chancellor of Germany, to attract German investors. Another fun fact? In 1930, Bismarck and Fargo had a dispute, known as the "Capitol Tower War," over which city should be the state capital.

6

Charleston, West Virginia

Did you know that the original name of West Virginia's capital was Charles Town in honor of the father of Colonel George Clendenin, one of the first settlers?

Charleston is best known for offering a unique combination of history, culture, and outdoor adventure.

7

Hartford, Connecticut

Founded in 1635, Connecticut's capital is one of the oldest cities in the U.S. Hartford is known for being a key cultural center in New England. It was the home of writer Mark Twain and is home to historic sites such as the State Capitol, the Harriet Beecher Stowe House, and Bushnell Park, the oldest public park in the country.

Hartford is also called the "insurance capital of the world" due to the presence of major insurance companies. But the city's most curious fact is that it was where Teddy Roosevelt, aboard the Columbia Electric Victoria Phaeton, took the first presidential automobile ride in history!

8

Harrisburg, Pennsylvania

Pennsylvania's capital city is best known for its role in the Civil War and the Underground Railroad. Located on the banks of the Susquehanna River, Harrisburg has been an important center of transportation and commerce. Today, it is known for its historic architecture, museums, and special events.

Harrisburg is also home to the longest stone arch bridge in the world, the Rockville Bridge, built in 1902. Oh, and in 1979, it came close to a nuclear disaster due to the accident at the Three Mile Island plant, the worst in U.S. history —but that's a longer story for another article!

9

Olympia, Washington

Located at the southern tip of Puget Sound, Washington's state capital is known for its natural beauty and vibrant culture. But did you know Olympia is the northernmost state capital in the contiguous U.S.?

Oh, and it's also a great place to try some of the best craft beer in the country.

10

Salt Lake City, Utah

Utah's state capital is popular for being one of the best places to ski in the United States. But that's not all! Salt Lake City is also the only state capital with three words in its name. Have you ever thought about that?

It has the largest Mormon population in the country and is the world headquarters of the Church of Jesus Christ of Latter-day Saints. Another fun fact? Salt Lake City is home to more plastic surgeons per capita than any other state capital!

11

Montpelier, Vermont

Named after the French city of the same name, Montpelier is the least populated state capital, with a population of just 7,900. Probably for that reason, Vermont's capital prides itself on its small local businesses: it is the only state capital that doesn't have a McDonald's or a Starbucks. Could you live without these fast food chains? It doesn't have a Walmart store either!

12

Topeka, Kansas

Topeka, Kansas’s state capital, has several interesting tidbits. For example, did you know its name, of Native American origin, means "a good place to dig potatoes"? Interesting, don’t you think?

In 2010, Topeka temporarily changed its name to "Google, Kansas" to attract the attention of the internet giant and become the capital city of fiber optics. Frivolous facts aside, Topeka was also very important in the history of the civil rights movement.
