| centimeter |
a unit of length equal to one hundredth of a meter or 0.3937 inch. (abbreviated: cm) |
| kilometer |
A kilometer is a unit of length in a system of measuring things that is called the "metric system." A kilometer is equal to one thousand "meters." A meter is the basic unit of length in the metric system. It is equal to a little more than three feet, about the length of some baseball bats. That means that one kilometer is equal in length to about one thousand baseball bats! One kilometer is shorter than a mile, though. It is only equal to about six tenths of a mile. A short way to write "kilometer" is "km." |
| m.1 |
abbreviation of "meter," or "meters." |
| meter1 |
A meter is a certain length. You might say that a baseball bat is one meter long, for example. When we measure something in meters, we are using a system of measuring called the metric system. When we use the metric system, we don't use measuring words like foot and inch. We use words like meter and centimeter. A meter is a little longer than three feet, and three feet is equal to 36 inches, about the length of some baseball bats. A short way to write meter is "m." |
| meter3 |
A meter is a device that measures distance, speed, time, quantity, or degree. |
| metre |
a spelling of "meter1" (unit of measure) and "meter2" (musical time) used in Canada and Britain. See "meter" for more information. |
| 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. |
