Meters to CM Converter
Convert meters to centimeters — a hundred to the meter, just a decimal shift. Results update as you type; exact factors shown.
One meter is 100 centimeters — see the exact factor, not a rounded rule of thumb.
How the meters to cm converter works
Every length is converted through the meter, the SI base unit of length. The inch has been defined as exactly 25.4 mm since the 1959 international yard and pound agreement, so a foot is exactly 0.3048 m, a yard 0.9144 m and a statute mile 1,609.344 m. The nautical mile is 1,852 m by international definition.
The US uses customary units (US gallon, short ton, °F) in daily life; NIST SP 811 gives the exact SI factors.
