## 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 220 feet per second into knots we have to multiply 220 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

220 ft/s → V(kt)

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

V(kt) = 220 ft/s × 0.59248380129641 kt

V(kt) = 130.34643628521 kt

The final result is:

220 ft/s → 130.34643628521 kt

We conclude that 220 feet per second is equivalent to 130.34643628521 knots:

220 feet per second = 130.34643628521 knots

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.007671862986817 × 220 feet per second.

Another way is saying that 220 feet per second is equal to 1 ÷ 0.007671862986817 knots.

## Approximate result

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

220 ft/s ≅ 130.346 kt

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