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 2221 feet per second into knots we have to multiply 2221 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

2221 ft/s → V_(kt)

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

V_(kt) = 2221 ft/s × 0.59248380129641 kt

V_(kt) = 1315.9065226793 kt

The final result is:

2221 ft/s → 1315.9065226793 kt

We conclude that 2221 feet per second is equivalent to 1315.9065226793 knots:

2221 feet per second = 1315.9065226793 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.00075993239851406 × 2221 feet per second.

Another way is saying that 2221 feet per second is equal to 1 ÷ 0.00075993239851406 knots.

Approximate result

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

2221 ft/s ≅ 1315.907 kt

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