Conversion Formula
The formula to convert pounds to newtons is: N = lb × 4.44822. This works because 1 pound-force is defined as the force needed to accelerate a pound of mass at 9.80665 m/s², which equals 4.44822 newtons. So, multiplying pounds by this factor gives the force in newtons.
For example, converting 10 lb: 10 × 4.44822 = 44.4822 N, which is the force exerted by 10 pounds of weight under Earth’s gravity.
Conversion Example
- Convert 5 lb to newtons:
- Multiply 5 by 4.44822
- 5 × 4.44822 = 22.2411 N
- Result: 5 lb equals approximately 22.24 newtons
- Convert 20 lb to newtons:
- Multiply 20 by 4.44822
- 20 × 4.44822 = 88.9644 N
- Result: 20 lb equals approximately 88.96 newtons
- Convert 15 lb to newtons:
- Multiply 15 by 4.44822
- 15 × 4.44822 = 66.7233 N
- Result: 15 lb equals approximately 66.72 newtons

Conversion Definitions
“lb” (pound) is a unit of weight or force measurement primarily used in the US, representing the force exerted by gravity on a pound of mass. “Newtons” are SI units of force, measuring the push or pull on an object, with 1 N equal to the force needed to accelerate 1 kg at 1 m/s².
Conversion FAQs
Why is the conversion factor 4.44822 for pounds to newtons?
This factor comes from the definition of pound-force, which is based on the force required to accelerate a pound mass at Earth’s gravity (9.80665 m/s²). Multiplying the pound by this factor converts it into the equivalent force in newtons.
Can I use a simple calculator to convert 10 lb to newtons?
Yes, entering 10 into a calculator and multiplying by 4.44822 will give you the force in newtons. This is straightforward but requires knowing the correct conversion factor to avoid errors.
Does the conversion change with location?
Since pounds-force are based on Earth’s gravity, the conversion is generally constant worldwide. However, actual weight may vary slightly depending on local gravity, but the standard conversion factor remains accurate for most calculations.
Are pounds and newtons interchangeable?
No, pounds are a unit of mass or force depending on context, while newtons are a SI force unit. Conversion between them depends on gravity, so always use the correct factor when converting force measurements.
What is the practical significance of converting pounds to newtons?
Converting to newtons allows for precise force calculations in scientific and engineering contexts, especially when using SI units, making it easier to perform calculations involving forces, stresses, and accelerations.
