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 644.2 knots into feet per second we have to multiply 644.2 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
644.2 kt → V(ft/s)
Solve the above proportion to obtain the velocity V in feet per second:
V(ft/s) = 644.2 kt × 1.6878098570997 ft/s
V(ft/s) = 1087.2871099437 ft/s
The final result is:
644.2 kt → 1087.2871099437 ft/s
We conclude that 644.2 knots is equivalent to 1087.2871099437 feet per second:
