Conversion formula
The conversion factor from knots to feet per second is 1.6878098570997, which means that 1 knot is equal to 1.6878098570997 feet per second:
1 kt = 1.6878098570997 ft/s
To convert 9 knots into feet per second we have to multiply 9 by the conversion factor in order to get the velocity amount from knots to feet per second. We can also form a simple proportion to calculate the result:
1 kt → 1.6878098570997 ft/s
9 kt → V(ft/s)
Solve the above proportion to obtain the velocity V in feet per second:
V(ft/s) = 9 kt × 1.6878098570997 ft/s
V(ft/s) = 15.190288713898 ft/s
The final result is:
9 kt → 15.190288713898 ft/s
We conclude that 9 knots is equivalent to 15.190288713898 feet per second:
9 knots = 15.190288713898 feet per second
Alternative conversion
We can also convert by utilizing the inverse value of the conversion factor. In this case 1 foot per second is equal to 0.065831533477379 × 9 knots.
Another way is saying that 9 knots is equal to 1 ÷ 0.065831533477379 feet per second.
Approximate result
For practical purposes we can round our final result to an approximate numerical value. We can say that nine knots is approximately fifteen point one nine feet per second:
9 kt ≅ 15.19 ft/s
An alternative is also that one foot per second is approximately zero point zero six six times nine knots.
