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 331 knots into feet per second we have to multiply 331 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

331 kt → V_(ft/s)

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

V_(ft/s) = 331 kt × 1.6878098570997 ft/s

V_(ft/s) = 558.66506270001 ft/s

The final result is:

331 kt → 558.66506270001 ft/s

We conclude that 331 knots is equivalent to 558.66506270001 feet per second:

331 knots = 558.66506270001 feet per second

Alternative conversion
