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 638.1 knots into feet per second we have to multiply 638.1 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
638.1 kt → V(ft/s)
Solve the above proportion to obtain the velocity V in feet per second:
V(ft/s) = 638.1 kt × 1.6878098570997 ft/s
V(ft/s) = 1076.9914698153 ft/s
The final result is:
638.1 kt → 1076.9914698153 ft/s
We conclude that 638.1 knots is equivalent to 1076.9914698153 feet per second:
638.1 knots = 1076.9914698153 feet per second
