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 663 knots into feet per second we have to multiply 663 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

663 kt → V_(ft/s)

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

V_(ft/s) = 663 kt × 1.6878098570997 ft/s

V_(ft/s) = 1119.0179352571 ft/s

The final result is:

663 kt → 1119.0179352571 ft/s

We conclude that 663 knots is equivalent to 1119.0179352571 feet per second:

663 knots = 1119.0179352571 feet per second

Alternative conversion
