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 709 feet per second into knots we have to multiply 709 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

709 ft/s → V_(kt)

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

V_(kt) = 709 ft/s × 0.59248380129641 kt

V_(kt) = 420.07101511915 kt

The final result is:

709 ft/s → 420.07101511915 kt

We conclude that 709 feet per second is equivalent to 420.07101511915 knots:

709 feet per second = 420.07101511915 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.00238054986897 × 709 feet per second.

Another way is saying that 709 feet per second is equal to 1 ÷ 0.00238054986897 knots.

Approximate result

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

709 ft/s ≅ 420.071 kt

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