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 638 knots into feet per second we have to multiply 638 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

638 kt → V_(ft/s)

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

V_(ft/s) = 638 kt × 1.6878098570997 ft/s

V_(ft/s) = 1076.8226888296 ft/s

The final result is:

638 kt → 1076.8226888296 ft/s

We conclude that 638 knots is equivalent to 1076.8226888296 feet per second:

638 knots = 1076.8226888296 feet per second
