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 129.9 knots into feet per second we have to multiply 129.9 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
129.9 kt → V(ft/s)
Solve the above proportion to obtain the velocity V in feet per second:
V(ft/s) = 129.9 kt × 1.6878098570997 ft/s
V(ft/s) = 219.24650043726 ft/s
The final result is:
129.9 kt → 219.24650043726 ft/s
We conclude that 129.9 knots is equivalent to 219.24650043726 feet per second:
129.9 knots = 219.24650043726 feet per second
Alternative conversion
