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 380.7 knots into feet per second we have to multiply 380.7 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

380.7 kt → V_(ft/s)

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

V_(ft/s) = 380.7 kt × 1.6878098570997 ft/s

V_(ft/s) = 642.54921259787 ft/s

The final result is:

380.7 kt → 642.54921259787 ft/s

We conclude that 380.7 knots is equivalent to 642.54921259787 feet per second:

380.7 knots = 642.54921259787 feet per second

Alternative conversion
