What density is used for brass?

The default density is 8.5 g/cm³, which is representative of common brass alloys such as CW614N (free-machining brass) and C360. Naval brass (C464) is slightly denser at ~8.53 g/cm³. You can enter a custom density for your specific alloy.

How is the cross-sectional area calculated?

The area formula for an L-section is (Leg A + Leg B − t) × t, where t is the wall thickness. This correctly subtracts the corner square counted in both legs, giving the true material cross-section.

Can I calculate weight for unequal angle bars?

Yes. Enter different values for Leg A and Leg B. The formula works for both equal-angle and unequal-angle brass sections.

What unit systems are supported?

You can work in millimeters for dimensions and meters for length (metric), or inches for dimensions and feet for length (imperial). Results are shown in kg or lb and kg/m or lb/ft respectively.

What is the linear weight output?

The linear weight (kg/m or lb/ft) tells you how much one unit of length weighs. This is useful when ordering stock material by the meter or foot without needing to specify a total length.

Why does thickness need to be less than both leg widths?

If the thickness equals or exceeds a leg width, the cross-section formula produces a zero or negative area, which is geometrically impossible for a standard angle bar. The calculator flags this as an input error.

Summary

Enter the leg widths, thickness, and length of a brass angle bar to instantly calculate its weight using brass density 8.5 g/cm³.

How it works

Enter the width of Leg A and Leg B (use equal values for equal-angle bars).
Enter the wall thickness of the angle bar.
Enter the total length of the bar.
Select your unit system — metric (mm / m) or imperial (in / ft).
The calculator derives the cross-sectional area, multiplies by length and density, and returns the total weight and linear weight per unit length.

Use cases

Estimate shipping or freight weight for brass structural profiles.
Calculate material cost by weight for machining and fabrication projects.
Verify supplier weight specifications for L-section brass stock.
Plan load-bearing designs using brass angle sections.
Compare equal vs. unequal leg brass angle options by weight.
Quick workshop estimation before cutting bar stock.
Assess brass vs. other alloy weights for material substitution.
