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 20.5 knots into feet per second we have to multiply 20.5 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

20.5 kt → V_(ft/s)

Solve the above proportion to obtain the velocity V in feet per second:

V_(ft/s) = 20.5 kt × 1.6878098570997 ft/s

V_(ft/s) = 34.600102070545 ft/s

The final result is:

20.5 kt → 34.600102070545 ft/s

We conclude that 20.5 knots is equivalent to 34.600102070545 feet per second:

20.5 knots = 34.600102070545 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 0.028901648843727 × 20.5 knots.

Another way is saying that 20.5 knots is equal to 1 ÷ 0.028901648843727 feet per second.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that twenty point five knots is approximately thirty-four point six feet per second:

20.5 kt ≅ 34.6 ft/s

An alternative is also that one foot per second is approximately zero point zero two nine times twenty point five knots.
