What density is used for copper?

The default density is 8.96 g/cm³ (8960 kg/m³), which is the standard value for commercially pure copper (C10100, C11000). You can enter a custom density for copper alloys such as brass (8.4–8.7 g/cm³) or bronze (8.7–8.9 g/cm³).

How is the I-beam cross-section area calculated?

The I-beam area uses the formula: Area = 2 × (flange width × flange thickness) + web thickness × (height − 2 × flange thickness). This counts both top and bottom flanges plus the web between them.

How is the rectangular beam area calculated?

For a solid rectangular beam the area is simply width × height. All material is assumed solid — use the I-beam type if you need to model an H-section profile.

What units are supported?

Metric (millimeters for cross-section, meters for length, kilograms for weight) and imperial (inches for cross-section, feet for length, pounds for weight). Switch with the unit toggle and all labels update instantly.

Can I get the linear weight (kg/m)?

Yes. The results panel shows both total weight and linear weight per unit length, which is useful for ordering standard stock lengths.

Why is copper so much heavier than aluminum?

Copper has a density of about 8.96 g/cm³ compared to aluminum's 2.70 g/cm³ — making copper roughly 3.3 times heavier for the same volume. This is an important consideration when substituting materials in structural or electrical designs.
