## Conversion formula

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 238.7 kilometers into millimeters we have to multiply 238.7 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

238.7 km → L(mm)

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

L(mm) = 238.7 km × 1000000 mm

L(mm) = 238700000 mm

The final result is:

238.7 km → 238700000 mm

We conclude that 238.7 kilometers is equivalent to 238700000 millimeters:
