## 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 40 centimeters into meters we have to multiply 40 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

40 cm → L(m)

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

L(m) = 40 cm × 0.01 m

L(m) = 0.4 m

The final result is:

40 cm → 0.4 m

We conclude that 40 centimeters is equivalent to 0.4 meters:

40 centimeters = 0.4 meters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 meter is equal to 2.5 × 40 centimeters.

Another way is saying that 40 centimeters is equal to 1 ÷ 2.5 meters.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that forty centimeters is approximately zero point four meters:

40 cm ≅ 0.4 m

An alternative is also that one meter is approximately two point five times forty centimeters.
