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 87 knots into feet per second we have to multiply 87 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

87 kt → V_(ft/s)

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

V_(ft/s) = 87 kt × 1.6878098570997 ft/s

V_(ft/s) = 146.83945756768 ft/s

The final result is:

87 kt → 146.83945756768 ft/s

We conclude that 87 knots is equivalent to 146.83945756768 feet per second:

87 knots = 146.83945756768 feet per second
