1. What Is The Specific Gravity To Density Formula?

The Specific Gravity To Density formula converts specific gravity (SG) to density in pounds per cubic inch (lb/in³). Specific gravity is a dimensionless unit defined as 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:

• \( density \) — Density of the substance (lb/in³)
• \( SG \) — Specific gravity of the substance (unitless)
• \( density_{water} \) — Density of water (0.036127 lb/in³)

Explanation: The formula multiplies the specific gravity by the density of water to obtain the absolute density of the substance in the desired units.

3. Importance Of Density Calculation

Details: Density calculation is essential in various fields including material science, engineering, and fluid mechanics for determining mass properties, buoyancy, and material selection.

4. Using The Calculator

Tips: Enter the specific gravity value (must be greater than 0). The calculator will compute the density in pounds per cubic inch.

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: Why use 0.036127 lb/in³ for water density?
A: This is the standard density of water at 4°C in pounds per cubic inch, which is commonly used as the reference value.

Q3: Can this formula be used for any material?
A: Yes, as long as you have the specific gravity value for that material relative to water.

Q4: How accurate is this conversion?
A: The conversion is mathematically exact when using the correct water density value. Accuracy depends on the precision of the specific gravity measurement.

Q5: What are typical specific gravity values?
A: Water has SG = 1. Most materials range from 0.5 (light woods) to 19+ (precious metals like gold).
