Why Don't the U.S., Myanmar, and Liberia Use the Metric System?

The U. S., Myanmar, and Liberia are like the only kids in class who still use inches instead of centimeters, just because they always have.

A long time ago, when these countries were building their systems of measurement, they chose feet, miles, pounds, and ounces as their standards. These measurements came from the way people lived back then, like how many steps you take to walk across a room or how much something weighs in your hand. It was simple and made sense for them.

But then, most of the world decided to switch to the metric system, which is based on tens (like 10 centimeters make a decimeter, and 100 centimeters make a meter). It’s like counting with hands, it’s easier when you count in groups of ten!

The U. S., Myanmar, and Liberia stayed behind because they had already built their lives around the old system. Changing to metric would be like asking everyone in class to switch from inches to centimeters all at once, even though most people would probably say “yes,” those three countries said “no” for a long time.

It’s not that the old system is bad, it just didn’t change, and sometimes being different isn’t bad either!
