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 90 knots into feet per second we have to multiply 90 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

90 kt → V_(ft/s)

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

V_(ft/s) = 90 kt × 1.6878098570997 ft/s

V_(ft/s) = 151.90288713898 ft/s

The final result is:

90 kt → 151.90288713898 ft/s

We conclude that 90 knots is equivalent to 151.90288713898 feet per second:

90 knots = 151.90288713898 feet per second

Alternative conversion
