Newtons to Pounds-force Converter
1 newton ≈ 0.224808943 pounds-force
A force, not a mass. The pound of mass is in the Weight category.
1 newton equals 0.224809 pounds-force
How to convert newtons to pounds-force
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.
lbf = N ÷ 4.448221615One pound-force corresponds to 4.448221615 newtons, so divide by that figure. Displayed constants may be rounded; the converter uses the stored factor before rounding the result.
2.24809 lbf ≈ 10 ÷ 4.448221615A 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.
