The conversion factor from kilometers to millimeters is 1000000, which means that 1 kilometer is equal to 1000000 millimeters:

1 km = 1000000 mm

To convert 422 kilometers into millimeters we have to multiply 422 by the conversion factor in order to get the length amount from kilometers to millimeters. We can also form a simple proportion to calculate the result:

1 km → 1000000 mm

422 km → L(mm)

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

L(mm) = 422 km × 1000000 mm

L(mm) = 422000000 mm

The final result is:

422 km → 422000000 mm

We conclude that 422 kilometers is equivalent to 422000000 millimeters:
