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 321 kilometers into meters we have to multiply 321 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

321 km → L_(m)

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

L_(m) = 321 km × 1000 m

L_(m) = 321000 m

The final result is:

321 km → 321000 m

We conclude that 321 kilometers is equivalent to 321000 meters:

321 kilometers = 321000 meters
