Conversion formula

The conversion factor from knots to feet per second is 1.6878098570997, which means that 1 knot is equal to 1.6878098570997 feet per second:

1 kt = 1.6878098570997 ft/s

To convert 631.5 knots into feet per second we have to multiply 631.5 by the conversion factor in order to get the velocity amount from knots to feet per second. We can also form a simple proportion to calculate the result:

1 kt → 1.6878098570997 ft/s

631.5 kt → V_(ft/s)

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

V_(ft/s) = 631.5 kt × 1.6878098570997 ft/s

V_(ft/s) = 1065.8519247585 ft/s

The final result is:

631.5 kt → 1065.8519247585 ft/s

We conclude that 631.5 knots is equivalent to 1065.8519247585 feet per second:

631.5 knots = 1065.8519247585 feet per second

Alternative conversion
