How do you calculate angle weight?

First find the L-section cross-section area: Area = (Leg A + Leg B − thickness) × thickness. Multiply area by bar length to get volume, then multiply volume by the bronze density (8.73 g/cm³) for the weight. Divide the total by length for weight per meter or per foot.

What density is used for bronze?

The default density is 8.73 g/cm³, which corresponds to commercial bronze (approximately UNS C22000, 90% copper / 10% zinc). You can override this value for other alloys — for example, phosphor bronze (C51000) is approximately 8.86 g/cm³ and aluminum bronze (C63000) is approximately 7.89 g/cm³.

How is the cross-sectional area calculated?

The cross-section area uses the standard L-section formula: Area = (Leg A + Leg B − t) × t, where t is the wall thickness. This correctly subtracts the corner region counted twice when both legs are added.

Can I calculate weight for unequal-leg bronze angle bars?

Yes. Enter different values for Leg A and Leg B. The formula handles both equal-leg and unequal-leg sections identically.

What unit systems are supported?

You can work in millimeters / meters / kilograms (metric) or inches / feet / pounds (imperial). Toggle the unit system and all labels and results update instantly.

Does the tool show linear weight?

Yes. The results panel displays both total weight and linear weight per unit length (kg/m or lb/ft), which is useful for ordering stock material by the meter or foot.
