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 21.7 knots into feet per second we have to multiply 21.7 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
21.7 kt → V(ft/s)
Solve the above proportion to obtain the velocity V in feet per second:
V(ft/s) = 21.7 kt × 1.6878098570997 ft/s
V(ft/s) = 36.625473899064 ft/s
The final result is:
21.7 kt → 36.625473899064 ft/s
We conclude that 21.7 knots is equivalent to 36.625473899064 feet per second:
21.7 knots = 36.625473899064 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 0.027303400981401 × 21.7 knots.
Another way is saying that 21.7 knots is equal to 1 ÷ 0.027303400981401 feet per second.
Approximate result
For practical purposes we can round our final result to an approximate numerical value. We can say that twenty-one point seven knots is approximately thirty-six point six two five feet per second:
21.7 kt ≅ 36.625 ft/s
An alternative is also that one foot per second is approximately zero point zero two seven times twenty-one point seven knots.
