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 390 feet per second into knots we have to multiply 390 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

390 ft/s → V(kt)

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

V(kt) = 390 ft/s × 0.59248380129641 kt

V(kt) = 231.0686825056 kt

The final result is:

390 ft/s → 231.0686825056 kt

We conclude that 390 feet per second is equivalent to 231.0686825056 knots:

390 feet per second = 231.0686825056 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.004327717582307 × 390 feet per second.

Another way is saying that 390 feet per second is equal to 1 ÷ 0.004327717582307 knots.

Approximate result

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

390 ft/s ≅ 231.069 kt

An alternative is also that one knot is approximately zero point zero zero four times three hundred ninety feet per second.
