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 428 feet per second into knots we have to multiply 428 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
428 ft/s → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 428 ft/s × 0.59248380129641 kt
V(kt) = 253.58306695486 kt
The final result is:
428 ft/s → 253.58306695486 kt
We conclude that 428 feet per second is equivalent to 253.58306695486 knots:
428 feet per second = 253.58306695486 knots
Alternative conversion
