1. What is a Specific Gravity to Density Calculator?

Definition: This calculator converts specific gravity (SG) to density in pounds per cubic inch (lb/in³).

Purpose: It helps material scientists, engineers, and construction professionals convert between these important material properties.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density (lb/in³)
• \( SG \) — Specific Gravity (unitless)
• \( 0.036127 \) — Conversion factor (density of water in lb/in³)

Explanation: Specific gravity is multiplied by the density of water to get the material's density in lb/in³.

3. Importance of Density Calculation

Details: Density is crucial for material selection, structural calculations, buoyancy assessments, and quality control.

4. Using the Calculator

Tips: Enter the specific gravity value (must be > 0). The calculator will output density in lb/in³.

5. Frequently Asked Questions (FAQ)

Q1: What is specific gravity?
A: Specific gravity is the ratio of a material's density to the density of water (at 4°C).

Q2: Why 0.036127 as the conversion factor?
A: This is the density of water in lb/in³ (1 g/cm³ = 0.036127 lb/in³).

Q3: What's a typical specific gravity for construction materials?
A: Concrete: ~2.4, Steel: ~7.85, Aluminum: ~2.7, Wood: 0.3-0.9 (varies by type).

Q4: Can I use this for liquids?
A: Yes, this works for any material as long as you know its specific gravity.

Q5: How precise is this conversion?
A: Very precise, as the water density factor is a defined constant.
