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 217.4 feet per second into knots we have to multiply 217.4 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

217.4 ft/s → V(kt)

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

V(kt) = 217.4 ft/s × 0.59248380129641 kt

V(kt) = 128.80597840184 kt

The final result is:

217.4 ft/s → 128.80597840184 kt

We conclude that 217.4 feet per second is equivalent to 128.80597840184 knots:

217.4 feet per second = 128.80597840184 knots
