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 30.9 feet per second into knots we have to multiply 30.9 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
30.9 ft/s → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 30.9 ft/s × 0.59248380129641 kt
V(kt) = 18.307749460059 kt
The final result is:
30.9 ft/s → 18.307749460059 kt
We conclude that 30.9 feet per second is equivalent to 18.307749460059 knots:
30.9 feet per second = 18.307749460059 knots
Alternative conversion
We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.054621678223292 × 30.9 feet per second.
Another way is saying that 30.9 feet per second is equal to 1 ÷ 0.054621678223292 knots.
Approximate result
For practical purposes we can round our final result to an approximate numerical value. We can say that thirty point nine feet per second is approximately eighteen point three zero eight knots:
30.9 ft/s ≅ 18.308 kt
An alternative is also that one knot is approximately zero point zero five five times thirty point nine feet per second.
