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 678 feet per second into knots we have to multiply 678 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

678 ft/s → V(kt)

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

V(kt) = 678 ft/s × 0.59248380129641 kt

V(kt) = 401.70401727896 kt

The final result is:

678 ft/s → 401.70401727896 kt

We conclude that 678 feet per second is equivalent to 401.70401727896 knots:

678 feet per second = 401.70401727896 knots
