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 681 knots into feet per second we have to multiply 681 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

681 kt → V_(ft/s)

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

V_(ft/s) = 681 kt × 1.6878098570997 ft/s

V_(ft/s) = 1149.3985126849 ft/s

The final result is:

681 kt → 1149.3985126849 ft/s

We conclude that 681 knots is equivalent to 1149.3985126849 feet per second:

681 knots = 1149.3985126849 feet per second
