1. What Is The Specific Gravity To Density Formula?

The Specific Gravity To Density formula converts specific gravity (SG) to density in pounds per gallon (lb/gal). 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/gal)
• \( SG \) — Specific gravity (unitless)
• \( density\_water \) — Density of water (8.345 lb/gal)

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

3. Importance Of Density Calculation

Details: Calculating density from specific gravity is essential in various industries such as petroleum, chemicals, and food processing for quality control, formulation, and compliance with specifications.

4. Using The Calculator

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

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 is water density 8.345 lb/gal?
A: This is the density of water at standard conditions (approximately 4°C or 39.2°F) in pounds per gallon.

Q3: Can this formula be used for any substance?
A: Yes, as long as the specific gravity is known relative to water, the formula applies to liquids and solids.

Q4: What are common applications?
A: Used in brewing, petroleum industry, chemical manufacturing, and any field where density conversion is needed.

Q5: How accurate is this calculation?
A: The accuracy depends on the precision of the specific gravity measurement and using the correct reference density for water.
