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 515 knots into feet per second we have to multiply 515 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

515 kt → V_(ft/s)

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

V_(ft/s) = 515 kt × 1.6878098570997 ft/s

V_(ft/s) = 869.22207640636 ft/s

The final result is:

515 kt → 869.22207640636 ft/s

We conclude that 515 knots is equivalent to 869.22207640636 feet per second:

515 knots = 869.22207640636 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 0.0011504539830998 × 515 knots.

Another way is saying that 515 knots is equal to 1 ÷ 0.0011504539830998 feet per second.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that five hundred fifteen knots is approximately eight hundred sixty-nine point two two two feet per second:

515 kt ≅ 869.222 ft/s

An alternative is also that one foot per second is approximately zero point zero zero one times five hundred fifteen knots.
