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 6240 kilometers into millimeters we have to multiply 6240 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

6240 km → L_(mm)

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

L_(mm) = 6240 km × 1000000 mm

L_(mm) = 6240000000 mm

The final result is:

6240 km → 6240000000 mm

We conclude that 6240 kilometers is equivalent to 6240000000 millimeters:
