1. What is Specific Gravity to Density Conversion?

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

Purpose: It helps engineers and material scientists quickly convert between these two 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 absolute density.

3. Importance of Density Calculation

Details: Density is crucial for material selection, buoyancy calculations, and structural design.

4. Using the Calculator

Tips: Enter the specific gravity value (must be > 0). The result will show 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 (62.428 lb/ft³ converted to lb/in³).

Q3: Can I use this for any material?
A: Yes, as long as you know its specific gravity relative to water.

Q4: How precise is this conversion?
A: Very precise, assuming standard temperature conditions (4°C for water reference).

Q5: What's the density of water in lb/in³?
A: Exactly 0.036127 lb/in³ (which is why we use this factor).
