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 641.4 knots into feet per second we have to multiply 641.4 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
641.4 kt → V(ft/s)
Solve the above proportion to obtain the velocity V in feet per second:
V(ft/s) = 641.4 kt × 1.6878098570997 ft/s
V(ft/s) = 1082.5612423438 ft/s
The final result is:
641.4 kt → 1082.5612423438 ft/s
We conclude that 641.4 knots is equivalent to 1082.5612423438 feet per second:
641.4 knots = 1082.5612423438 feet per second
