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 51.5 feet per second into knots we have to multiply 51.5 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

51.5 ft/s → V_(kt)

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

V_(kt) = 51.5 ft/s × 0.59248380129641 kt

V_(kt) = 30.512915766765 kt

The final result is:

51.5 ft/s → 30.512915766765 kt

We conclude that 51.5 feet per second is equivalent to 30.512915766765 knots:

51.5 feet per second = 30.512915766765 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.032773006933975 × 51.5 feet per second.

Another way is saying that 51.5 feet per second is equal to 1 ÷ 0.032773006933975 knots.

Approximate result

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

51.5 ft/s ≅ 30.513 kt

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