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 640.4 feet per second into meters per second we have to multiply 640.4 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

640.4 ft/s → V_(m/s)

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

V_(m/s) = 640.4 ft/s × 0.3048 m/s

V_(m/s) = 195.19392 m/s

The final result is:

640.4 ft/s → 195.19392 m/s

We conclude that 640.4 feet per second is equivalent to 195.19392 meters per second:

640.4 feet per second = 195.19392 meters per second

Alternative conversion
