About Density & Specific Gravity Converter
Understanding Density and Specific Gravity
Density and specific gravity are fundamental properties that describe the relationship between mass and volume of materials. While density provides an absolute measure (mass per unit volume), specific gravity offers a relative measure compared to a reference substance (usually water). These properties are crucial in engineering, manufacturing, and scientific research, helping us understand material behavior and characteristics.
Common Material Densities
| Material | Density (g/cm³) | Specific Gravity |
|---|---|---|
| Water (4°C) | 1.000 | 1.000 |
| Mercury | 13.546 | 13.546 |
| Aluminum | 2.700 | 2.700 |
| Ice | 0.917 | 0.917 |
