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 feet per second into knots we have to multiply 138 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 ft/s → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 138 ft/s × 0.59248380129641 kt
V(kt) = 81.762764578904 kt
The final result is:
138 ft/s → 81.762764578904 kt
We conclude that 138 feet per second is equivalent to 81.762764578904 knots:
138 feet per second = 81.762764578904 knots
Alternative conversion
We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.012230506210868 × 138 feet per second.
Another way is saying that 138 feet per second is equal to 1 ÷ 0.012230506210868 knots.
Approximate result
For practical purposes we can round our final result to an approximate numerical value. We can say that one hundred thirty-eight feet per second is approximately eighty-one point seven six three knots:
138 ft/s ≅ 81.763 kt
An alternative is also that one knot is approximately zero point zero one two times one hundred thirty-eight feet per second.
