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 28.1 knots into feet per second we have to multiply 28.1 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

28.1 kt → V_(ft/s)

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

V_(ft/s) = 28.1 kt × 1.6878098570997 ft/s

V_(ft/s) = 47.427456984503 ft/s

The final result is:

28.1 kt → 47.427456984503 ft/s

We conclude that 28.1 knots is equivalent to 47.427456984503 feet per second:

28.1 knots = 47.427456984503 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 0.021084832786349 × 28.1 knots.

Another way is saying that 28.1 knots is equal to 1 ÷ 0.021084832786349 feet per second.

Approximate result

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

28.1 kt ≅ 47.427 ft/s

An alternative is also that one foot per second is approximately zero point zero two one times twenty-eight point one knots.
