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 421.2 knots into feet per second we have to multiply 421.2 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
421.2 kt → V(ft/s)
Solve the above proportion to obtain the velocity V in feet per second:
V(ft/s) = 421.2 kt × 1.6878098570997 ft/s
V(ft/s) = 710.90551181041 ft/s
The final result is:
421.2 kt → 710.90551181041 ft/s
We conclude that 421.2 knots is equivalent to 710.90551181041 feet per second:
421.2 knots = 710.90551181041 feet per second
Alternative conversion
