This calculator provides a simple way to convert the specific weight of a material from kilonewtons per cubic meter (kN/m³) to pounds-force per cubic foot (lbf/ft³). This is a common conversion needed in civil and structural engineering when working with both metric and imperial unit systems.
Conversion Formula
The calculation is based on the direct conversion factor between the two units:
γ (lbf/ft³) = γ (kN/m³) × 6.36588
Where:
- γ (lbf/ft³) is the specific weight in pounds-force per cubic foot.
- γ (kN/m³) is the specific weight in kilonewtons per cubic meter.
Example
Let's convert the typical specific weight of reinforced concrete, which is 23.5 kN/m³, to lbf/ft³.
Calculation:
23.5 kN/m³ × 6.36588 = 149.598 lbf/ft³
The calculator will also show the result in pounds-force per cubic inch (lbf/in³) for convenience.
