1. What is Metal Density Conversion?

Definition: This calculator converts density values from kilograms per cubic meter (kg/m³) to grams per cubic centimeter (g/cm³) for metals.

Purpose: It helps engineers, metallurgists, and material scientists work with density measurements in different unit systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density in g/cm³
• \( \rho_{kg/m³} \) — Density in kg/m³

Explanation: Since 1 g/cm³ equals 1000 kg/m³, we divide the kg/m³ value by 1000 to get the equivalent in g/cm³.

3. Common Metal Densities

Examples:

• Steel: ~7.85 g/cm³ (7850 kg/m³)
• Brass: ~8.5 g/cm³ (8500 kg/m³)
• Aluminum: ~2.7 g/cm³ (2700 kg/m³)
• Copper: ~8.96 g/cm³ (8960 kg/m³)
• Lead: ~11.34 g/cm³ (11340 kg/m³)

4. Using the Calculator

Tips: Enter the density value in kg/m³. The calculator will automatically convert it to g/cm³. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why convert between these units?
A: Different industries use different units - construction often uses kg/m³ while material science prefers g/cm³.

Q2: How precise are these conversions?
A: The conversion is mathematically exact, but actual metal densities vary slightly by alloy composition.

Q3: Does temperature affect density?
A: Yes, metals expand with heat, slightly decreasing density at higher temperatures.

Q4: Where can I find density values for specific alloys?
A: Consult material data sheets or engineering reference manuals for exact values.

Q5: Can I convert g/cm³ back to kg/m³?
A: Yes, simply multiply the g/cm³ value by 1000 to get kg/m³.
