The conversion of 15 newtons (N) equals approximately 3.37 pounds-force (lbf).
To convert newtons to pounds-force, you multiply the value in newtons by the factor 0.224809. This is because one newton is defined as the force needed to accelerate a 1 kg mass at 1 m/s², while one pound-force is the force required to accelerate a 1 lb mass at standard gravity. The conversion factor accounts for the difference in units and gravity standards.

Conversion Formula
The formula to convert newtons to pounds-force is: lbf = N × 0.224809. This works because 1 N equals approximately 0.224809 lbf, based on the definition of pound-force, which is the force exerted by gravity on a one-pound mass at standard gravity (32.174 ft/s²). By multiplying the newton value by this factor, you change the unit from N to lbf. For example, for 15 N: 15 × 0.224809 = 3.372 lbf.
Conversion Example
- Convert 10 N:
- Using the formula: 10 × 0.224809
- Calculates to 2.2481 lbf
- Convert 25 N:
- 10 × 0.224809 = 5.6202
- Then, 25 × 0.224809 = 5.6202 lbf
- Convert 50 N:
- 50 × 0.224809 = 11.24045
- Convert 5 N:
- 5 × 0.224809 = 1.1240 lbf
- Convert 100 N:
- 100 × 0.224809 = 22.4809 lbf
