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 420 feet per second into meters per second we have to multiply 420 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

420 ft/s → V_(m/s)

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

V_(m/s) = 420 ft/s × 0.3048 m/s

V_(m/s) = 128.016 m/s

The final result is:

420 ft/s → 128.016 m/s

We conclude that 420 feet per second is equivalent to 128.016 meters per second:

420 feet per second = 128.016 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 0.0078115235595551 × 420 feet per second.

Another way is saying that 420 feet per second is equal to 1 ÷ 0.0078115235595551 meters per second.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that four hundred twenty feet per second is approximately one hundred twenty-eight point zero one six meters per second:

420 ft/s ≅ 128.016 m/s

An alternative is also that one meter per second is approximately zero point zero zero eight times four hundred twenty feet per second.
