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 1421 kilometers per hour into meters per second we have to multiply 1421 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

1421 km/h → V(m/s)

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

V(m/s) = 1421 km/h × 0.277777777778 m/s

V(m/s) = 394.72222222254 m/s

The final result is:

1421 km/h → 394.72222222254 m/s

We conclude that 1421 kilometers per hour is equivalent to 394.72222222254 meters per second:

1421 kilometers per hour = 394.72222222254 meters per second

Alternative conversion
