Conversion Formula
The formula to convert pounds to newtons is force (N) = mass (lbs) * 4.44822. This works because a pound-force is defined as the force required to accelerate a one-pound mass at 32.174 ft/s2. The factor 4.44822 converts the imperial pound-force into the metric newton. For example, for 10 lbs: 10 * 4.44822 = 44.4822 N.
Conversion Example
- Convert 15 lbs to newtons:
- 15 * 4.44822 = 66.7233 N
- Convert 50 lbs to newtons:
- 50 * 4.44822 = 222.411 N
- Convert 5 lbs to newtons:
- 5 * 4.44822 = 22.2411 N
- Convert 100 lbs to newtons:
- 100 * 4.44822 = 444.822 N

Conversion Definitions
lbs
Lbs, short for pounds, is a unit of weight or force in the Imperial system; one pound-force (lbf) equals the force needed to accelerate one pound mass at standard gravity, serving as a standard measure for weight in the US customary system.
newtons
Newtons are the SI unit of force, defined as the force required to accelerate a 1-kilogram mass at 1 meter per second squared, providing a standardized metric measurement for forces across scientific and engineering fields.
Conversion FAQs
Why does 20 lbs equal approximately 89 newtons?
This is because each pound-force is exactly 4.44822 newtons, so multiplying 20 by this factor gives about 88.9644 newtons. Small rounding differences might make it appear as 89, but the precise value is close to this number.
Can I convert pounds to newtons without a calculator?
While a calculator makes it easier, you can estimate by multiplying pounds by 4.45, which gives a close approximation. For precise work, however, using the exact conversion factor 4.44822 is recommended for accuracy.
Does the conversion change if gravity varies?
Yes, because pounds-force depend on standard gravity (9.80665 m/s2). If gravity changes, the force in newtons would also change proportionally, but in most contexts, standard gravity is assumed for conversions.
Is the conversion different for mass and weight?
Yes, pounds can refer to mass (pounds-mass) or force (pounds-force). The conversion to newtons applies to pounds-force, which is a measure of weight or force, not mass. For mass conversions, different calculations are used.
