America is just about the only country in the world to be using feet, pounds, and inches to measure distance and weight. This system is called English measurement. Most of the rest of the world uses the metric system. It uses meters, hectares, and liters to measure stuff. The histries of the English and metric systems are interesting and why America still uses the English system is too.
America used the English system after the metric system was invented in the 1860s. The metric system makes alot of sense. It is based on the number ten. Everything is ten of this equals one of that. So, ten centimeters equals one decimeter. The same thing works for weight and volume.
When America was started, it was as a colony of the English. So we used the same measurement as the English. It use to be that these measurements were based on changing things, like the length of a king’s foot, or the length of his step. As the years went by those distances became set to avoid confusion. After all its hard to build a house if ten feet now is different than ten feet five years ago.
Despite how much sense it makes, the metric system never catched on in America. Every few years they try to make students learn it. It never seems to work everyone thinks in terms of inches and gallons and pounds not centimeters and liters and grams.
Will America ever switch over? I don’t know. Especially because of the rest of the world. All the scientists do and we’ll need to be able to use it as well as everyone else if we’re going to stay the biggest, powerfulest country. When we all learn about the two systems it shows us how interesting they are.
