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 139 feet per second into knots we have to multiply 139 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

139 ft/s → V_(kt)

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

V_(kt) = 139 ft/s × 0.59248380129641 kt

V_(kt) = 82.355248380201 kt

The final result is:

139 ft/s → 82.355248380201 kt

We conclude that 139 feet per second is equivalent to 82.355248380201 knots:

139 feet per second = 82.355248380201 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.012142516957552 × 139 feet per second.

Another way is saying that 139 feet per second is equal to 1 ÷ 0.012142516957552 knots.

Approximate result

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

139 ft/s ≅ 82.355 kt

An alternative is also that one knot is approximately zero point zero one two times one hundred thirty-nine feet per second.
