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 840 feet per second into knots we have to multiply 840 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
840 ft/s → V(kt)
Solve the above proportion to obtain the velocity V in knots:
V(kt) = 840 ft/s × 0.59248380129641 kt
V(kt) = 497.68639308898 kt
The final result is:
840 ft/s → 497.68639308898 kt
We conclude that 840 feet per second is equivalent to 497.68639308898 knots:
840 feet per second = 497.68639308898 knots
Alternative conversion
