Conversion formula

The conversion factor from feet per second to meters per second is 0.3048, which means that 1 foot per second is equal to 0.3048 meters per second:

1 ft/s = 0.3048 m/s

To convert 21 feet per second into meters per second we have to multiply 21 by the conversion factor in order to get the velocity amount from feet per second to meters per second. We can also form a simple proportion to calculate the result:

1 ft/s → 0.3048 m/s

21 ft/s → V(m/s)

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

V(m/s) = 21 ft/s × 0.3048 m/s

V(m/s) = 6.4008 m/s

The final result is:

21 ft/s → 6.4008 m/s

We conclude that 21 feet per second is equivalent to 6.4008 meters per second:

21 feet per second = 6.4008 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 0.1562304711911 × 21 feet per second.

Another way is saying that 21 feet per second is equal to 1 ÷ 0.1562304711911 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 feet per second is approximately six point four zero one meters per second:

21 ft/s ≅ 6.401 m/s

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