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 171.3 knots into feet per second we have to multiply 171.3 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

171.3 kt → V_(ft/s)

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

V_(ft/s) = 171.3 kt × 1.6878098570997 ft/s

V_(ft/s) = 289.12182852119 ft/s

The final result is:

171.3 kt → 289.12182852119 ft/s

We conclude that 171.3 knots is equivalent to 289.12182852119 feet per second:

171.3 knots = 289.12182852119 feet per second
