Conversion Formula
The formula to convert pounds to newtons is simple: multiply the number of pounds by 4.44822. This works because 1 lb-force equals 4.44822 newtons, a fixed conversion factor derived from the definition of the pound-force. For example, converting 10 lb:
- 10 lb × 4.44822 = 44.4822 newtons
Conversion Example
- Convert 5 lb to newtons:
- Step 1: Take 5 lb
- Step 2: Multiply by 4.44822
- Step 3: 5 × 4.44822 = 22.2411 newtons
- Convert 20 lb to newtons:
- Step 1: Take 20 lb
- Step 2: Multiply by 4.44822
- Step 3: 20 × 4.44822 = 88.9644 newtons
- Convert 15 lb to newtons:
- Step 1: Take 15 lb
- Step 2: Multiply by 4.44822
- Step 3: 15 × 4.44822 = 66.7233 newtons

Conversion Definitions
“lb” (pound) is a unit of force in the imperial system, measuring the weight exerted by gravity on a mass. A pound-force equals the force needed to accelerate a one-pound mass by gravity at Earth’s surface, roughly 4.44822 newtons.
“Newtons” (N) is the SI unit for force, representing the force needed to accelerate a 1-kilogram mass at 1 meter per second squared. It quantifies force, weight, or push, and is widely used in physics and engineering.
Conversion FAQs
How accurate is the conversion factor between lb and newtons?
The conversion factor of 4.44822 is precise, based on the exact definition of the pound-force. It is accepted internationally and used in scientific calculations for accurate force conversions between imperial and SI units.
Does the conversion change with location on Earth?
Practically, yes. The force of gravity varies slightly around Earth, so the actual force in newtons for a given mass in pounds can differ marginally depending on location. However, the standard conversion uses Earth’s average gravity for consistency.
Can I use this conversion for mass instead of force?
No, because pounds can measure both mass and force depending on context. To convert mass in pounds to kilograms, divide by 2.20462. To convert force in pounds-force to newtons, use the factor 4.44822. They are different measurements.
What is the significance of using newtons instead of pounds?
Newtons are part of the SI system, providing a standardized measure of force used globally in science and engineering. Pounds are primarily used in the US customary system, so converting to newtons allows for international consistency and precision.
