What density does this calculator use?

It uses 8.73 g/cm³ (8730 kg/m³), which is the standard density for common bronze alloys such as C932 (SAE 660), C954 aluminum bronze, and C220 commercial bronze. Exact density can vary slightly by alloy, but 8.73 g/cm³ is a reliable general-purpose value.

Can I use imperial units?

Yes. Switch to Imperial mode and enter width and thickness in inches and length in feet. The calculator converts all inputs to centimeters internally and returns weight in both lb and kg.

What is the weight formula for a bronze flat bar?

Weight = Width × Thickness × Length × Density. In metric: convert all dimensions to centimeters, multiply to get volume in cm³, then multiply by 8.73 g/cm³ to get grams, and divide by 1000 for kilograms.

How does bronze density compare to aluminum or steel?

Bronze at 8.73 g/cm³ is roughly 3.2 times denser than aluminum (2.70 g/cm³) and slightly lighter than steel (7.85–8.05 g/cm³ depending on grade). A bronze bar of the same dimensions will weigh about 3× more than an equivalent aluminum bar.

How do I calculate weight for multiple bars?

Enter the dimensions of a single bar and set the Quantity field to the number of bars. The calculator multiplies the per-bar weight by the quantity and displays the total automatically.

Does alloy grade affect the result?

Minor alloy variations can shift density by 1–3%. For example, phosphor bronze (C544) is around 8.80 g/cm³ and silicon bronze is closer to 8.53 g/cm³. For most practical purposes, 8.73 g/cm³ is a safe default estimate.
