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 1090 feet per second into knots we have to multiply 1090 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

1090 ft/s → V(kt)

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

V(kt) = 1090 ft/s × 0.59248380129641 kt

V(kt) = 645.80734341309 kt

The final result is:

1090 ft/s → 645.80734341309 kt

We conclude that 1090 feet per second is equivalent to 645.80734341309 knots:

1090 feet per second = 645.80734341309 knots
