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 646 feet per second into knots we have to multiply 646 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
646 ft/s → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 646 ft/s × 0.59248380129641 kt
V(kt) = 382.74453563748 kt
The final result is:
646 ft/s → 382.74453563748 kt
We conclude that 646 feet per second is equivalent to 382.74453563748 knots:
646 feet per second = 382.74453563748 knots
Alternative conversion
