## 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 488 kilometers into millimeters we have to multiply 488 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

488 km → L(mm)

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

L(mm) = 488 km × 1000000 mm

L(mm) = 488000000 mm

The final result is:

488 km → 488000000 mm

We conclude that 488 kilometers is equivalent to 488000000 millimeters:

488 kilometers = 488000000 millimeters
