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 249 kilometers into millimeters we have to multiply 249 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

249 km → L(mm)

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

L(mm) = 249 km × 1000000 mm

L(mm) = 249000000 mm

The final result is:

249 km → 249000000 mm

We conclude that 249 kilometers is equivalent to 249000000 millimeters:
