Conversion formula

The conversion factor from millimeters to kilometers is 1.0E-6, which means that 1 millimeter is equal to 1.0E-6 kilometers:

1 mm = 1.0E-6 km

To convert 212 millimeters into kilometers we have to multiply 212 by the conversion factor in order to get the length amount from millimeters to kilometers. We can also form a simple proportion to calculate the result:

1 mm → 1.0E-6 km

212 mm → L_(km)

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

L_(km) = 212 mm × 1.0E-6 km

L_(km) = 0.000212 km

The final result is:

212 mm → 0.000212 km

We conclude that 212 millimeters is equivalent to 0.000212 kilometers:

212 millimeters = 0.000212 kilometers
