## 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 28.5 feet per second into knots we have to multiply 28.5 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

28.5 ft/s → V(kt)

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

V(kt) = 28.5 ft/s × 0.59248380129641 kt

V(kt) = 16.885788336948 kt

The final result is:

28.5 ft/s → 16.885788336948 kt

We conclude that 28.5 feet per second is equivalent to 16.885788336948 knots:

28.5 feet per second = 16.885788336948 knots

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.059221398494728 × 28.5 feet per second.

Another way is saying that 28.5 feet per second is equal to 1 ÷ 0.059221398494728 knots.

## Approximate result

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

28.5 ft/s ≅ 16.886 kt

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