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 489 feet per second into knots we have to multiply 489 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
489 ft/s → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 489 ft/s × 0.59248380129641 kt
V(kt) = 289.72457883394 kt
The final result is:
489 ft/s → 289.72457883394 kt
We conclude that 489 feet per second is equivalent to 289.72457883394 knots:
489 feet per second = 289.72457883394 knots
Alternative conversion
