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 31.5 knots into feet per second we have to multiply 31.5 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

31.5 kt → V_(ft/s)

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

V_(ft/s) = 31.5 kt × 1.6878098570997 ft/s

V_(ft/s) = 53.166010498642 ft/s

The final result is:

31.5 kt → 53.166010498642 ft/s

We conclude that 31.5 knots is equivalent to 53.166010498642 feet per second:

31.5 knots = 53.166010498642 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 0.018809009564965 × 31.5 knots.

Another way is saying that 31.5 knots is equal to 1 ÷ 0.018809009564965 feet per second.

Approximate result

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

31.5 kt ≅ 53.166 ft/s

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