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 8.1 feet per second into knots we have to multiply 8.1 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
8.1 ft/s → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 8.1 ft/s × 0.59248380129641 kt
V(kt) = 4.7991187905009 kt
The final result is:
8.1 ft/s → 4.7991187905009 kt
We conclude that 8.1 feet per second is equivalent to 4.7991187905009 knots:
8.1 feet per second = 4.7991187905009 knots
Alternative conversion
We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.20837158729626 × 8.1 feet per second.
Another way is saying that 8.1 feet per second is equal to 1 ÷ 0.20837158729626 knots.
Approximate result
For practical purposes we can round our final result to an approximate numerical value. We can say that eight point one feet per second is approximately four point seven nine nine knots:
8.1 ft/s ≅ 4.799 kt
An alternative is also that one knot is approximately zero point two zero eight times eight point one feet per second.
