Conversion Formula
The formula to convert pounds to newtons is: Force (N) = weight in lbs × 4.44822. This works because pounds-force is a unit of force, and multiplying it by 4.44822 converts it to newtons, the SI unit of force. For example, with 168 lbs:
- 168 lbs × 4.44822 = 747.7 N
This method ensures accurate conversions because it directly relates the imperial unit of force to the metric unit.

Conversion Definitions
lbs
Lbs, or pounds, is a unit of mass or weight traditionally used in the imperial system; it measures how heavy an object is. When used in force contexts, it often refers to pound-force, representing the gravitational force on a pound-mass under Earth’s gravity.
newtons
Newtons are the SI unit of force, named after Sir Isaac Newton. It measures the force needed to accelerate a one-kilogram mass by one meter per second squared. One newton equals the force required to produce an acceleration of 1 m/s² on a 1 kg mass.
Conversion FAQs
Why do I need to multiply pounds by 4.44822 to get newtons?
This multiplication converts the force measured in pound-force to the SI unit of force, newtons, because 1 lbf equals approximately 4.44822 N. This factor ensures consistent, accurate force conversions across systems.
Can I convert pounds to newtons for mass measurements?
No, pounds measure mass or weight, whereas newtons measure force. To convert mass to force, you need to consider gravity. The conversion from pounds mass to newtons involves multiplying the mass in pounds by 4.44822 and accounting for gravity, if needed.
Is 168 lbs the same as 168 pounds-force?
Not necessarily. If referring to weight under Earth’s gravity, 168 pounds typically means pound-force, which is force. But if referring to mass, 168 lbs is a mass measurement, requiring conversion to force via gravity for force calculations.
How accurate is the conversion factor 4.44822?
The factor 4.44822 is an approximation based on the definition of pound-force and the newton. It provides precise enough results for most practical purposes, but slight variations may occur depending on measurement standards or conditions.
