What density is used for zinc?

The calculator uses the standard density of zinc: 7.133 g/cm³ (7133 kg/m³). This is the widely accepted value for commercially pure zinc (Zn).

Does this work for zinc alloys?

This tool uses the density of commercially pure zinc. Zinc alloys such as Zamak have slightly different densities (typically 6.6–6.9 g/cm³). Use this tool as an estimate for alloys and adjust if you need more precision.

Can I use decimal values?

Yes. You can enter decimal values for width, thickness, and length (e.g., 25.4 mm width, 6.35 mm thickness, 1.5 m length).

What is the formula used?

Weight = width × thickness × length × density. All dimensions are converted to centimeters before calculation, and the zinc density (7.133 g/cm³) is applied to produce grams, which are then converted to kg and lb.

How is this different from a round bar calculator?

A flat bar has a rectangular cross-section (width × thickness), while a round bar uses a circular cross-section (π × r²). This calculator uses the rectangular cross-section formula appropriate for flat stock.

Summary

Enter the width, thickness, and length of a zinc flat bar to instantly calculate its weight in kg or lb.

How it works

Select your preferred unit system (metric or imperial).
Enter the width of the zinc flat bar.
Enter the thickness of the zinc flat bar.
Enter the length of the zinc flat bar.
Optionally enter a quantity if calculating for multiple bars.
The calculator multiplies width × thickness × length to get volume, then applies zinc density (7.133 g/cm³) to get weight in kg and lb.

Use cases
