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 677.4 knots into feet per second we have to multiply 677.4 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

677.4 kt → V_(ft/s)

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

V_(ft/s) = 677.4 kt × 1.6878098570997 ft/s

V_(ft/s) = 1143.3223971994 ft/s

The final result is:

677.4 kt → 1143.3223971994 ft/s

We conclude that 677.4 knots is equivalent to 1143.3223971994 feet per second:

677.4 knots = 1143.3223971994 feet per second
