Conversion formula

The conversion factor from kilometers to meters is 1000, which means that 1 kilometer is equal to 1000 meters:

1 km = 1000 m

To convert 428.4 kilometers into meters we have to multiply 428.4 by the conversion factor in order to get the length amount from kilometers to meters. We can also form a simple proportion to calculate the result:

1 km → 1000 m

428.4 km → L_(m)

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

L_(m) = 428.4 km × 1000 m

L_(m) = 428400 m

The final result is:

428.4 km → 428400 m

We conclude that 428.4 kilometers is equivalent to 428400 meters:
