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 2157 feet per second into knots we have to multiply 2157 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

2157 ft/s → V_(kt)

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

V_(kt) = 2157 ft/s × 0.59248380129641 kt

V_(kt) = 1277.9875593964 kt

The final result is:

2157 ft/s → 1277.9875593964 kt

We conclude that 2157 feet per second is equivalent to 1277.9875593964 knots:

2157 feet per second = 1277.9875593964 knots
