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 646.1 knots into feet per second we have to multiply 646.1 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
646.1 kt → V(ft/s)
Solve the above proportion to obtain the velocity V in feet per second:
V(ft/s) = 646.1 kt × 1.6878098570997 ft/s
V(ft/s) = 1090.4939486721 ft/s
The final result is:
646.1 kt → 1090.4939486721 ft/s
We conclude that 646.1 knots is equivalent to 1090.4939486721 feet per second:
