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 674.9 knots into feet per second we have to multiply 674.9 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

674.9 kt → V_(ft/s)

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

V_(ft/s) = 674.9 kt × 1.6878098570997 ft/s

V_(ft/s) = 1139.1028725566 ft/s

The final result is:

674.9 kt → 1139.1028725566 ft/s

We conclude that 674.9 knots is equivalent to 1139.1028725566 feet per second:

674.9 knots = 1139.1028725566 feet per second
