| metric system |
The metric system is a way to measure things. It's a way to measure how long something is, for example, or how heavy or how tall. It's also a way to measure how much of something there is--like how much water there is in a bottle or how much peanut butter there is in a jar. In America, people use words like inches, feet, miles, pounds, and ounces when they measure things, but the metric system uses different words, and they don't mean the same things. The metric system uses words like meter, gram, and liter for measuring things. The metric system is used by people of most countries of the world to measure things around them. And the metric system is used by scientists of all countries in their work. |
