1. What Is Density Calculation With Specific Gravity?

Density calculation using specific gravity is a method to determine the density of a substance relative to the density of water. Specific gravity is a dimensionless quantity that represents the ratio of a substance's density to that of water.

2. How Does The Calculator Work?

The calculator uses the density formula:

Where:

• \( SG \) — Specific Gravity (dimensionless)
• \( 1000 \) — Density of water in kg/m³

Explanation: The formula converts specific gravity to density by multiplying by the density of water (1000 kg/m³).

3. Importance Of Density Calculation

Details: Density calculation is essential in various fields including engineering, chemistry, and material science. It helps determine buoyancy, material purity, and is used in quality control processes.

4. Using The Calculator

Tips: Enter specific gravity as a decimal value (e.g., 1.025 for seawater). The value must be greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is specific gravity?
A: Specific gravity is the ratio of the density of a substance to the density of a reference substance (typically water at 4°C).

Q2: Why multiply by 1000?
A: Water has a density of 1000 kg/m³, so multiplying specific gravity by 1000 converts it to absolute density in kg/m³.

Q3: Can specific gravity be less than 1?
A: Yes, substances less dense than water (like most oils) have specific gravity values less than 1.

Q4: What are common specific gravity values?
A: Pure water: 1.0, Seawater: ~1.025, Alcohol: ~0.79, Mercury: ~13.6.

Q5: How is specific gravity measured?
A: Typically using a hydrometer or digital density meter that compares the substance's density to water.
