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 81 feet per second into knots we have to multiply 81 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
81 ft/s → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 81 ft/s × 0.59248380129641 kt
V(kt) = 47.991187905009 kt
The final result is:
81 ft/s → 47.991187905009 kt
We conclude that 81 feet per second is equivalent to 47.991187905009 knots:
81 feet per second = 47.991187905009 knots
Alternative conversion
We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.020837158729626 × 81 feet per second.
Another way is saying that 81 feet per second is equal to 1 ÷ 0.020837158729626 knots.
Approximate result
For practical purposes we can round our final result to an approximate numerical value. We can say that eighty-one feet per second is approximately forty-seven point nine nine one knots:
81 ft/s ≅ 47.991 kt
An alternative is also that one knot is approximately zero point zero two one times eighty-one feet per second.
