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 680.8 knots into feet per second we have to multiply 680.8 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
680.8 kt → V(ft/s)
Solve the above proportion to obtain the velocity V in feet per second:
V(ft/s) = 680.8 kt × 1.6878098570997 ft/s
V(ft/s) = 1149.0609507135 ft/s
The final result is:
680.8 kt → 1149.0609507135 ft/s
We conclude that 680.8 knots is equivalent to 1149.0609507135 feet per second:
680.8 knots = 1149.0609507135 feet per second
