Conversion formula

The conversion factor from kilometers per hour to meters per second is 0.277777777778, which means that 1 kilometer per hour is equal to 0.277777777778 meters per second:

1 km/h = 0.277777777778 m/s

To convert 8421 kilometers per hour into meters per second we have to multiply 8421 by the conversion factor in order to get the velocity amount from kilometers per hour to meters per second. We can also form a simple proportion to calculate the result:

1 km/h → 0.277777777778 m/s

8421 km/h → V_(m/s)

Solve the above proportion to obtain the velocity V in meters per second:

V_(m/s) = 8421 km/h × 0.277777777778 m/s

V_(m/s) = 2339.1666666685 m/s

The final result is:

8421 km/h → 2339.1666666685 m/s

We conclude that 8421 kilometers per hour is equivalent to 2339.1666666685 meters per second:

8421 kilometers per hour = 2339.1666666685 meters per second

Alternative conversion
