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 123 millimeters into meters we have to multiply 123 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

123 mm → L_(m)

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

L_(m) = 123 mm × 0.001 m

L_(m) = 0.123 m

The final result is:

123 mm → 0.123 m

We conclude that 123 millimeters is equivalent to 0.123 meters:

123 millimeters = 0.123 meters
