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 688 feet per second into knots we have to multiply 688 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
688 ft/s → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 688 ft/s × 0.59248380129641 kt
V(kt) = 407.62885529193 kt
The final result is:
688 ft/s → 407.62885529193 kt
We conclude that 688 feet per second is equivalent to 407.62885529193 knots:
688 feet per second = 407.62885529193 knots
Alternative conversion
