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 309 knots into feet per second we have to multiply 309 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
309 kt → V(ft/s)
Solve the above proportion to obtain the velocity V in feet per second:
V(ft/s) = 309 kt × 1.6878098570997 ft/s
V(ft/s) = 521.53324584382 ft/s
The final result is:
309 kt → 521.53324584382 ft/s
We conclude that 309 knots is equivalent to 521.53324584382 feet per second:
309 knots = 521.53324584382 feet per second
Alternative conversion
