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 39.5 knots into feet per second we have to multiply 39.5 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
39.5 kt → V(ft/s)
Solve the above proportion to obtain the velocity V in feet per second:
V(ft/s) = 39.5 kt × 1.6878098570997 ft/s
V(ft/s) = 66.66848935544 ft/s
The final result is:
39.5 kt → 66.66848935544 ft/s
We conclude that 39.5 knots is equivalent to 66.66848935544 feet per second:
39.5 knots = 66.66848935544 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 0.014999589906238 × 39.5 knots.
Another way is saying that 39.5 knots is equal to 1 ÷ 0.014999589906238 feet per second.
Approximate result
For practical purposes we can round our final result to an approximate numerical value. We can say that thirty-nine point five knots is approximately sixty-six point six six eight feet per second:
39.5 kt ≅ 66.668 ft/s
An alternative is also that one foot per second is approximately zero point zero one five times thirty-nine point five knots.
