Conversion formula

The conversion factor from feet per second to knots is 0.59248380129641, which means that 1 foot per second is equal to 0.59248380129641 knots:

1 ft/s = 0.59248380129641 kt

To convert 31.8 feet per second into knots we have to multiply 31.8 by the conversion factor in order to get the velocity amount from feet per second to knots. We can also form a simple proportion to calculate the result:

1 ft/s → 0.59248380129641 kt

31.8 ft/s → V(kt)

Solve the above proportion to obtain the velocity V in knots:

V(kt) = 31.8 ft/s × 0.59248380129641 kt

V(kt) = 18.840984881226 kt

The final result is:

31.8 ft/s → 18.840984881226 kt

We conclude that 31.8 feet per second is equivalent to 18.840984881226 knots:

31.8 feet per second = 18.840984881226 knots Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.053075781669803 × 31.8 feet per second.

Another way is saying that 31.8 feet per second is equal to 1 ÷ 0.053075781669803 knots.

Approximate result

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

31.8 ft/s ≅ 18.841 kt

An alternative is also that one knot is approximately zero point zero five three times thirty-one point eight feet per second.
