Pounds-force to Kilonewtons Converter
1 pound-force ≈ 0.00444822162 kilonewtons
A force, not a mass. The pound of mass is in the Weight category.
1 pound-force equals 0.00444822 kilonewtons
How to convert pounds-force to kilonewtons
Force is distinct from mass. Kilogram-force and pound-force use standard gravity, 9.80665 m/s²; calculating the weight of an actual mass at a location requires that location’s acceleration due to gravity.
kN = lbf × 0.004448221615One pound-force is 0.004448221615 kilonewtons, so a single multiplication converts any value.
0.0444822 kN ≈ 10 × 0.004448221615A force, not a mass. The pound of mass is in the Weight category.

Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
