## 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 21.5 kilometers per hour into meters per second we have to multiply 21.5 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

21.5 km/h → V(m/s)

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

V(m/s) = 21.5 km/h × 0.277777777778 m/s

V(m/s) = 5.972222222227 m/s

The final result is:

21.5 km/h → 5.972222222227 m/s

We conclude that 21.5 kilometers per hour is equivalent to 5.972222222227 meters per second:

21.5 kilometers per hour = 5.972222222227 meters per second

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 meter per second is equal to 0.16744186046498 × 21.5 kilometers per hour.

Another way is saying that 21.5 kilometers per hour is equal to 1 ÷ 0.16744186046498 meters per second.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that twenty-one point five kilometers per hour is approximately five point nine seven two meters per second:

21.5 km/h ≅ 5.972 m/s

An alternative is also that one meter per second is approximately zero point one six seven times twenty-one point five kilometers per hour.
