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 387.4 knots into feet per second we have to multiply 387.4 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

387.4 kt → V_(ft/s)

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

V_(ft/s) = 387.4 kt × 1.6878098570997 ft/s

V_(ft/s) = 653.85753864044 ft/s

The final result is:

387.4 kt → 653.85753864044 ft/s

We conclude that 387.4 knots is equivalent to 653.85753864044 feet per second:

387.4 knots = 653.85753864044 feet per second

Alternative conversion
