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) and may give slightly different results. Use this tool as an estimate for alloys.

Can I use decimal values?

Yes. You can enter decimal values for both diameter and length (e.g., 12.5 mm diameter, 1.75 m length).

What is the formula used?

Weight = π × (diameter/2)² × length × density. The diameter and length are converted to centimeters before calculation, and density is applied in g/cm³ to produce grams, which are then converted to kg and lb.

Are there size limits?

No hard limits are enforced, but the tool is designed for practical engineering sizes. Very small or very large values are accepted as long as they are positive numbers.
