A centimeter is a unit of length that is one hundredth of a meter. It’s the equivalent of a quarter inch, or just under three millimeters. Centimeters are used in many areas of science and engineering, including astronomy, geology, archaeology and measuring objects like car engines and medical implants. They’re also sometimes used in everyday life to measure things like the width of a door or the distance between two points.

A meter is the basic unit of measurement in the metric system. Originally, meters were the length of a pendulum that shook each time it hit a floor or a beam. The original metric system was based on the length of a pendulum and consisted of 1/10 000th of a kilometer (or one tenth of a millimeter). Today, meters are used to measure everything from length to volume to temperature. Meter is a unit of measurement that originated in ancient India. It was primarily used to measure liquids, such as water and rice wine, but it has since been adapted for other uses. In particular, meter is the standard by which length and weight are measured. Today, meter is most commonly used to measure electricity, gas and water. Butmeter has also been adopted by some industries as their preferred standard for measuring quantities such as freight volume, material flow or production output.
