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 389.3 knots into feet per second we have to multiply 389.3 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
389.3 kt → V(ft/s)
Solve the above proportion to obtain the velocity V in feet per second:
V(ft/s) = 389.3 kt × 1.6878098570997 ft/s
V(ft/s) = 657.06437736893 ft/s
The final result is:
389.3 kt → 657.06437736893 ft/s
We conclude that 389.3 knots is equivalent to 657.06437736893 feet per second:
