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 691 feet per second into knots we have to multiply 691 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
691 ft/s → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 691 ft/s × 0.59248380129641 kt
V(kt) = 409.40630669582 kt
The final result is:
691 ft/s → 409.40630669582 kt
We conclude that 691 feet per second is equivalent to 409.40630669582 knots:
691 feet per second = 409.40630669582 knots
Alternative conversion
