Specific gravity is a measure of density relative to water. It is dimensionless, meaning it has no units. When stated in the context of grams, it compares the density of a material in grams per cubic centimeter (g/cm³) to the density of water, which is 1 g/cm³ at 4°C. This comparison helps in identifying the relative heaviness of the material.
FAQs & Answers
- How is specific gravity calculated? Specific gravity is calculated by dividing the density of the material by the density of water at a specified temperature.
- Why is specific gravity important? Specific gravity helps identify materials’ relative heaviness, which is crucial in various scientific and engineering applications.
- Is specific gravity the same as density? No, specific gravity is a dimensionless quantity that denotes the ratio of a material's density to that of water, making it independent of units.
- What units are used for specific gravity? Specific gravity is dimensionless and typically used alongside grams per cubic centimeter (g/cm³) for measurements.
