Conversion formula

The conversion factor from centimeters to meters is 0.01, which means that 1 centimeter is equal to 0.01 meters:

1 cm = 0.01 m

To convert 21 centimeters into meters we have to multiply 21 by the conversion factor in order to get the length amount from centimeters to meters. We can also form a simple proportion to calculate the result:

1 cm → 0.01 m

21 cm → L_(m)

Solve the above proportion to obtain the length L in meters:

L_(m) = 21 cm × 0.01 m

L_(m) = 0.21 m

The final result is:

21 cm → 0.21 m

We conclude that 21 centimeters is equivalent to 0.21 meters:

21 centimeters = 0.21 meters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 meter is equal to 4.7619047619048 × 21 centimeters.
