1. What is Specific Gravity to lb/ft³ Conversion?

Definition: This calculator converts specific gravity (SG) to density in pounds per cubic foot (lb/ft³).

Purpose: It helps engineers, scientists, and technicians quickly convert between these common units of material density.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density (lb/ft³)
• \( SG \) — Specific Gravity (unitless)
• 62.4 — Density of water (lb/ft³ at standard conditions)

Explanation: Specific gravity is multiplied by the density of water to obtain the material's density.

3. Importance of Density Conversion

Details: Accurate density values are crucial for buoyancy calculations, material selection, and structural design.

4. Using the Calculator

Tips: Simply enter the specific gravity value (must be > 0) and the calculator will provide the equivalent density in lb/ft³.

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 standard conditions.

Q2: Why 62.4 lb/ft³?
A: This is the density of water at 4°C (39.2°F) and standard atmospheric pressure.

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

Q4: What's a typical specific gravity for common materials?
A: Examples: Aluminum (2.7), Steel (7.85), Concrete (2.4), Wood (0.3-0.9).

Q5: How precise is this conversion?
A: Very precise, assuming standard conditions and accurate SG value.
