1. What is Specific Gravity Weight Calculation?

The weight calculation from specific gravity determines the mass of a substance based on its volume and specific gravity relative to water. Specific gravity is the ratio of the density of a substance to the density of water.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Volume \) — Volume in cubic centimeters (cm³)
• \( SG \) — Specific gravity (dimensionless)
• \( Density\_water \) — Density of water (typically 1 g/cm³ at 4°C)

Explanation: The formula multiplies the volume by the specific gravity and water density to determine the actual weight of the substance.

3. Importance of Weight Calculation

Details: Calculating weight from specific gravity is essential in chemistry, material science, and engineering for determining mass when direct measurement isn't possible.

4. Using the Calculator

Tips: Enter volume in cm³, specific gravity (unitless), and water density (typically 1 g/cm³). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is specific gravity?
A: Specific gravity is the ratio of a substance's density to the density of water at a specified temperature.

Q2: Why use 1 g/cm³ for water density?
A: Pure water has a density of 1 g/cm³ at 4°C, which is the standard reference temperature for specific gravity measurements.

Q3: Can I use different units?
A: The calculator uses cm³ and grams for consistency. Convert other units before calculation (1 mL = 1 cm³ for water).

Q4: What affects specific gravity?
A: Temperature and pressure affect both the substance's density and water's density, thus affecting specific gravity.

Q5: When is this calculation most useful?
A: Particularly useful for liquids and irregularly shaped solids where direct weighing is impractical.
