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 128.9 feet per second into knots we have to multiply 128.9 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
128.9 ft/s → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 128.9 ft/s × 0.59248380129641 kt
V(kt) = 76.371161987107 kt
The final result is:
128.9 ft/s → 76.371161987107 kt
We conclude that 128.9 feet per second is equivalent to 76.371161987107 knots:
128.9 feet per second = 76.371161987107 knots
