1. What is Density Calculation Using Specific Gravity?

Density calculation using specific gravity is a method to determine the density of a substance by multiplying its specific gravity (relative to a reference substance) by the density of the reference substance (typically water at 4°C).

2. How Does the Calculator Work?

The calculator uses the density formula:

Where:

• \( SG \) — Specific Gravity (dimensionless)
• \( ref\_density \) — Reference Density (kg/m³)

Explanation: Specific gravity is the ratio of the density of a substance to the density of a reference substance. Multiplying specific gravity by the reference density gives the actual density of the substance.

3. Importance of Density Calculation

Details: Accurate density calculation is crucial for various scientific and industrial applications, including material identification, quality control, fluid mechanics, and buoyancy calculations.

4. Using the Calculator

Tips: Enter specific gravity (dimensionless) and reference density in kg/m³. All values must be valid (greater than 0). For water at 4°C, use reference density = 1000 kg/m³.

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: What reference density should I use?
A: For most applications, use 1000 kg/m³ (density of water at 4°C). For specialized applications, use the appropriate reference substance density.

Q3: Can I use this for gases as well as liquids?
A: Yes, the formula works for both liquids and gases, but ensure you're using the appropriate reference density for your application.

Q4: How accurate is this calculation?
A: The accuracy depends on the precision of your specific gravity measurement and the accuracy of the reference density value.

Q5: What are common units for density?
A: Common units include kg/m³, g/cm³, and lb/ft³. This calculator uses kg/m³, but you can convert results as needed.
