Conversion formula
The conversion factor from knots to feet per second is 1.6878098570997, which means that 1 knot is equal to 1.6878098570997 feet per second:
1 kt = 1.6878098570997 ft/s
To convert 685 knots into feet per second we have to multiply 685 by the conversion factor in order to get the velocity amount from knots to feet per second. We can also form a simple proportion to calculate the result:
1 kt → 1.6878098570997 ft/s
685 kt → V(ft/s)
Solve the above proportion to obtain the velocity V in feet per second:
V(ft/s) = 685 kt × 1.6878098570997 ft/s
V(ft/s) = 1156.1497521133 ft/s
The final result is:
685 kt → 1156.1497521133 ft/s
We conclude that 685 knots is equivalent to 1156.1497521133 feet per second:
