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 140 knots into feet per second we have to multiply 140 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

140 kt → V(ft/s)

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

V(ft/s) = 140 kt × 1.6878098570997 ft/s

V(ft/s) = 236.29337999396 ft/s

The final result is:

140 kt → 236.29337999396 ft/s

We conclude that 140 knots is equivalent to 236.29337999396 feet per second:

140 knots = 236.29337999396 feet per second
