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 1257 knots into feet per second we have to multiply 1257 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

1257 kt → V_(ft/s)

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

V_(ft/s) = 1257 kt × 1.6878098570997 ft/s

V_(ft/s) = 2121.5769903744 ft/s

The final result is:

1257 kt → 2121.5769903744 ft/s

We conclude that 1257 knots is equivalent to 2121.5769903744 feet per second:

1257 knots = 2121.5769903744 feet per second

Alternative conversion
