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 21.4 feet per second into knots we have to multiply 21.4 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
21.4 ft/s → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 21.4 ft/s × 0.59248380129641 kt
V(kt) = 12.679153347743 kt
The final result is:
21.4 ft/s → 12.679153347743 kt
We conclude that 21.4 feet per second is equivalent to 12.679153347743 knots:
21.4 feet per second = 12.679153347743 knots
Alternative conversion
We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.078869619490642 × 21.4 feet per second.
Another way is saying that 21.4 feet per second is equal to 1 ÷ 0.078869619490642 knots.
Approximate result
For practical purposes we can round our final result to an approximate numerical value. We can say that twenty-one point four feet per second is approximately twelve point six seven nine knots:
21.4 ft/s ≅ 12.679 kt
An alternative is also that one knot is approximately zero point zero seven nine times twenty-one point four feet per second.
