Conversion formula

The conversion factor from millimeters to meters is 0.001, which means that 1 millimeter is equal to 0.001 meters:

1 mm = 0.001 m

To convert 100 millimeters into meters we have to multiply 100 by the conversion factor in order to get the length amount from millimeters to meters. We can also form a simple proportion to calculate the result:

1 mm → 0.001 m

100 mm → L_(m)

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

L_(m) = 100 mm × 0.001 m

L_(m) = 0.1 m

The final result is:

100 mm → 0.1 m

We conclude that 100 millimeters is equivalent to 0.1 meters:

100 millimeters = 0.1 meters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 meter is equal to 10 × 100 millimeters.

Another way is saying that 100 millimeters is equal to 1 ÷ 10 meters.

Approximate result

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

100 mm ≅ 0.1 m

An alternative is also that one meter is approximately ten times one hundred millimeters.
