The unit "cm" stands for centimeter, which is a metric unit of length. One centimeter is equal to one hundredth of a meter. It is commonly used worldwide, except in a few countries like the United States where the inch is more common. To clarify the abbreviation:
- cm = centimeter
- 1 cm = 0.01 meters
If the question is specifically "how many cm is one inch?" the answer is exactly 2.54 centimeters per inch. The formula to convert inches to centimeters is:
centimeters=inches×2.54\text{centimeters}=\text{inches}\times 2.54centimeters=inches×2.54
This conversion is exact and widely used for length measurements.
