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 138.4 feet per second into knots we have to multiply 138.4 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
138.4 ft/s → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 138.4 ft/s × 0.59248380129641 kt
V(kt) = 81.999758099423 kt
The final result is:
138.4 ft/s → 81.999758099423 kt
We conclude that 138.4 feet per second is equivalent to 81.999758099423 knots:
138.4 feet per second = 81.999758099423 knots
