What density value does this calculator use?

The calculator uses 2500 kg/m³, which is the standard density for soda-lime glass — the most common type used for architectural and structural glass angle bars.

How is the L-section area calculated?

The cross-sectional area of an L-section is: (Leg A × thickness) + (Leg B × thickness) − (thickness²). The subtraction prevents the corner intersection from being counted twice.

Can I use this for other glass types?

The formula is correct for any uniform-density material. Borosilicate glass has a density of about 2230 kg/m³ and tempered glass is still ~2500 kg/m³. If your glass has a different density, the result will be proportionally different.

What if both legs have different thicknesses?

This calculator assumes a uniform thickness across both legs, which is the standard for extruded or machined glass angle bars. If your bar has unequal leg thicknesses, calculate each leg as a rectangular section separately and add the volumes.

What units can I use for input?

All inputs are in millimeters by default. The bar length field also accepts meters via a unit toggle. The output is always shown in both kg and lbs.
