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 678 kilometers per hour into meters per second we have to multiply 678 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

678 km/h → V_(m/s)

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

V_(m/s) = 678 km/h × 0.277777777778 m/s

V_(m/s) = 188.33333333348 m/s

The final result is:

678 km/h → 188.33333333348 m/s

We conclude that 678 kilometers per hour is equivalent to 188.33333333348 meters per second:

678 kilometers per hour = 188.33333333348 meters per second
