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 315 knots into feet per second we have to multiply 315 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

315 kt → V_(ft/s)

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

V_(ft/s) = 315 kt × 1.6878098570997 ft/s

V_(ft/s) = 531.66010498642 ft/s

The final result is:

315 kt → 531.66010498642 ft/s

We conclude that 315 knots is equivalent to 531.66010498642 feet per second:

315 knots = 531.66010498642 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 0.0018809009564965 × 315 knots.

Another way is saying that 315 knots is equal to 1 ÷ 0.0018809009564965 feet per second.

Approximate result

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

315 kt ≅ 531.66 ft/s

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