1. What is Metal Density?

Definition: Density is the mass per unit volume of a material, measured in kilograms per cubic meter (kg/m³).

Purpose: Understanding metal density is crucial for material selection, engineering calculations, and construction projects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density (kg/m³)
• \( m \) — Mass (kg)
• \( V \) — Volume (m³)

Explanation: The mass is divided by volume to calculate the material's density.

3. Common Metal Densities

Examples:

• Steel: ~7850 kg/m³
• Copper: ~8960 kg/m³
• Aluminum: ~2700 kg/m³
• Lead: ~11340 kg/m³
• Gold: ~19300 kg/m³

4. Using the Calculator

Tips: Enter the mass in kilograms and volume in cubic meters. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is density important in metalworking?
A: Density affects weight calculations, structural design, buoyancy, and material selection for specific applications.

Q2: How does temperature affect metal density?
A: Density decreases with temperature increase as metals expand (volume increases while mass stays constant).

Q3: What's the difference between density and specific gravity?
A: Specific gravity is density relative to water (dimensionless), while density has units (kg/m³).

Q4: How accurate are standard density values?
A: They're averages - actual density varies with alloy composition, impurities, and temperature.

Q5: Can I use this for non-metallic materials?
A: Yes, the formula works for any material, though typical densities will differ.
