To convert pound force to kilonewtons, multiply by 0.004448221615.
The calculation uses 1 lbf = 0.004448221615 kN. Results are displayed to at most 10 significant digits. Definitions can be exact while a displayed decimal is rounded. Match the displayed precision to your original measurement.
The formula
value in kN = value in lbf × 0.004448221615
lbf- Input unit: pound force
kN- Output unit: kilonewtons
How to use this calculator
- Enter a value in lbf.
- Multiply by the stored conversion factor.
- Read the result in kN; divide by the same factor to convert back.
