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 450 millimeters into kilometers we have to multiply 450 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

450 mm → L_(km)

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

L_(km) = 450 mm × 1.0E-6 km

L_(km) = 0.00045 km

The final result is:

450 mm → 0.00045 km

We conclude that 450 millimeters is equivalent to 0.00045 kilometers:

450 millimeters = 0.00045 kilometers
