Aluminum Flat Bar Weight Calculator

Summary

Enter width, thickness, and length of an aluminum flat bar to instantly calculate its weight using the standard density of 2.70 g/cm³.

How it works

1. Enter the flat bar width in millimeters or inches.
2. Enter the flat bar thickness in millimeters or inches.
3. Enter the total length in meters, millimeters, or feet.
4. Select your preferred unit system (metric or imperial).
5. The calculator multiplies Width × Thickness × Length × Density (2.70 g/cm³) to give weight in kg and lb.

Use cases

• Estimate material weight before ordering aluminum stock.
• Calculate dead load contribution of structural flat bars.
• Compare weight across different flat bar sizes for a design.
• Verify shipping weight for freight cost estimation.
• Check weight budget when designing lightweight assemblies.
• Quick sanity-check during fabrication planning.
