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 857.4 knots into feet per second we have to multiply 857.4 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

857.4 kt → V_(ft/s)

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

V_(ft/s) = 857.4 kt × 1.6878098570997 ft/s

V_(ft/s) = 1447.1281714773 ft/s

The final result is:

857.4 kt → 1447.1281714773 ft/s

We conclude that 857.4 knots is equivalent to 1447.1281714773 feet per second:

857.4 knots = 1447.1281714773 feet per second
