Conversion formula
The conversion factor from feet per second to knots is 0.59248380129641, which means that 1 foot per second is equal to 0.59248380129641 knots:
1 ft/s = 0.59248380129641 kt
To convert 421.3 feet per second into knots we have to multiply 421.3 by the conversion factor in order to get the velocity amount from feet per second to knots. We can also form a simple proportion to calculate the result:
1 ft/s → 0.59248380129641 kt
421.3 ft/s → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 421.3 ft/s × 0.59248380129641 kt
V(kt) = 249.61342548618 kt
The final result is:
421.3 ft/s → 249.61342548618 kt
We conclude that 421.3 feet per second is equivalent to 249.61342548618 knots:
421.3 feet per second = 249.61342548618 knots
