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 657 knots into feet per second we have to multiply 657 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

657 kt → V_(ft/s)

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

V_(ft/s) = 657 kt × 1.6878098570997 ft/s

V_(ft/s) = 1108.8910761145 ft/s

The final result is:

657 kt → 1108.8910761145 ft/s

We conclude that 657 knots is equivalent to 1108.8910761145 feet per second:

657 knots = 1108.8910761145 feet per second

Alternative conversion
