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 678.4 knots into feet per second we have to multiply 678.4 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
678.4 kt → V(ft/s)
Solve the above proportion to obtain the velocity V in feet per second:
V(ft/s) = 678.4 kt × 1.6878098570997 ft/s
V(ft/s) = 1145.0102070565 ft/s
The final result is:
678.4 kt → 1145.0102070565 ft/s
We conclude that 678.4 knots is equivalent to 1145.0102070565 feet per second:
678.4 knots = 1145.0102070565 feet per second
