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 684.4 knots into feet per second we have to multiply 684.4 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
684.4 kt → V(ft/s)
Solve the above proportion to obtain the velocity V in feet per second:
V(ft/s) = 684.4 kt × 1.6878098570997 ft/s
V(ft/s) = 1155.1370661991 ft/s
The final result is:
684.4 kt → 1155.1370661991 ft/s
We conclude that 684.4 knots is equivalent to 1155.1370661991 feet per second:
684.4 knots = 1155.1370661991 feet per second
