# cm to m

There are 0.01 centimeters (cm) in a meter (m), or 100 centimeters in 1 meter. The meter, or metre, is the base unit of length in the International System of units (SI). A centimeter is a unit of length in the metric system of measurement.

## Centimeters to meters converter

The following converter can convert from centimeters to meters or meters to centimeters. Just enter a value in either centimeters or meters to convert between the two.

### How many cm in a m

There are 100 centimeters in 1 m, or:

100 cm = 1 m

### How many m in a cm

There are 0.01 meters in 1 centimeter, or:

0.01 m = 1 cm

## How to convert cm to m

To convert cm to m, divide a value in centimeters by 100. To convert m to cm, multiply a value in meters by 100.

### cm to m formula

The formula for converting centimeters to meters is:

Similarly, the formula for converting meters to centimeters is:

Below are some cm to m conversion examples.

Examples

1. Convert 127.5 cm to m:

2. Convert 0.075 m to cm:

0.075 m × 100 = 7.5 cm

## What is a centimeter

A centimeter is a measurement of length in the International System of Units (SI).

### Centimeter definition

A centimeter is defined as one-hundredth of a meter, the base unit of length in SI. The definition of the meter is the distance traveled by light in a vacuum over of a second.

The International System of units uses a set of prefixes to relate a unit to its base unit by a power of 10. For example, the "centi-" prefix indicates that the unit that follows is of the base unit, so "centimeter" translates to one-hundredth of a meter. Similarly, a centiliter is equal to one-hundredth of a liter.

## What is a meter

A meter is the base unit of length in the International System of Units (SI). This means that other measurements of length are related to the meter by some power of 10.

### Definition of the meter

The meter is defined as the length of the path traveled by light in a vacuum over the course of of a second.

The definition of the meter has changed many times throughout the course of history in order to reduce uncertainty in its definition. Some of its past definitions include a definition based on a seconds pendulum, the quarter meridian, a physical prototype, the wavelength of the krypton-86 atom, and more.

## Difference between centimeters and meters

The only difference between centimeters and meters is the size of the unit of measurement. They are both measurements of length in the International System of Units (SI). The meter is the base unit of length in SI and the centimeter is one-hundredth of a meter.

Generally, centimeters are used for smaller measurements of length while meters are used for larger measurements of length. Both are typically used to measure objects or distances that can be seen by the human eye. For example, both meters and centimeters are commonly used to measure height in most parts of the world that use SI. Many track and field events measure distance in meters, while centimeters are used to measure things like shoe sizes, clothing measurements, and more.
