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 5.1 knots into feet per second we have to multiply 5.1 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

5.1 kt → V(ft/s)

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

V(ft/s) = 5.1 kt × 1.6878098570997 ft/s

V(ft/s) = 8.6078302712087 ft/s

The final result is:

5.1 kt → 8.6078302712087 ft/s

We conclude that 5.1 knots is equivalent to 8.6078302712087 feet per second:

5.1 knots = 8.6078302712087 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 0.11617329437184 × 5.1 knots.

Another way is saying that 5.1 knots is equal to 1 ÷ 0.11617329437184 feet per second.

Approximate result

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

5.1 kt ≅ 8.608 ft/s

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