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 438 knots into feet per second we have to multiply 438 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
438 kt → V(ft/s)
Solve the above proportion to obtain the velocity V in feet per second:
V(ft/s) = 438 kt × 1.6878098570997 ft/s
V(ft/s) = 739.26071740968 ft/s
The final result is:
438 kt → 739.26071740968 ft/s
We conclude that 438 knots is equivalent to 739.26071740968 feet per second:
438 knots = 739.26071740968 feet per second
