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 665 knots into feet per second we have to multiply 665 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

665 kt → V_(ft/s)

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

V_(ft/s) = 665 kt × 1.6878098570997 ft/s

V_(ft/s) = 1122.3935549713 ft/s

The final result is:

665 kt → 1122.3935549713 ft/s

We conclude that 665 knots is equivalent to 1122.3935549713 feet per second:

665 knots = 1122.3935549713 feet per second

Alternative conversion
