Formula & How It Works
Volumetric Mass Density Formula
Defines mass per unit volume. Source: NIST SP 811.
Worked Examples
Calculating Density of Gold Nugget
Input: Mass = 193g, Volume = 10 cm³
Explanation: 193 / 10 = 19.3 g/cm³ (pure gold density).
Frequently Asked Questions
Why does ice float on water?▼
Because ice has a lower density (~0.917 g/cm³) than liquid water (1.000 g/cm³).
Quick Reference & Conversion Table
| Material | Density (g/cm³) | Density (kg/m³) |
|---|---|---|
| Air (20°C) | 0.0012 | 1.20 |
| Pure Water (4°C) | 1.000 | 1,000 |
| Aluminum | 2.700 | 2,700 |
| Steel / Iron | 7.850 | 7,850 |
| Gold | 19.320 | 19,320 |
⚠️ Common Pitfalls to Avoid
- •Mixing mismatched units (e.g. dividing pounds by cubic centimeters without converting).
💡 Practical Real-World Uses
- •Identifying mineral ores and metals by checking specific gravity.
- •Calculating shipping weights based on material volume.
