Conversion formula
The conversion factor from feet per second to knots is 0.59248380129641, which means that 1 foot per second is equal to 0.59248380129641 knots:
1 ft/s = 0.59248380129641 kt
To convert 661 feet per second into knots we have to multiply 661 by the conversion factor in order to get the velocity amount from feet per second to knots. We can also form a simple proportion to calculate the result:
1 ft/s → 0.59248380129641 kt
661 ft/s → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 661 ft/s × 0.59248380129641 kt
V(kt) = 391.63179265693 kt
The final result is:
661 ft/s → 391.63179265693 kt
We conclude that 661 feet per second is equivalent to 391.63179265693 knots:
661 feet per second = 391.63179265693 knots
