1. What is Density Conversion (lb/gal to kg/m³)?

Definition: This calculator converts density measurements from pounds per gallon (lb/gal) to kilograms per cubic meter (kg/m³).

Purpose: It helps scientists, engineers, and professionals working with fluids to convert between these common density units.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \rho_{kg/m³} = \rho_{lb/gal} \times 119.826 \]

Where:

\( \rho_{kg/m³} \) — Density in kilograms per cubic meter
\( \rho_{lb/gal} \) — Density in pounds per gallon

Explanation: The conversion factor 119.826 comes from the relationship between pounds, gallons, kilograms, and cubic meters.

3. Importance of Density Conversion

Details: Accurate density conversions are essential for international projects, scientific research, and engineering calculations where different unit systems are used.

4. Using the Calculator

Tips: Simply enter the density value in pounds per gallon (lb/gal) and click "Convert" to get the equivalent in kilograms per cubic meter (kg/m³).

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 119.826?
A: This factor accounts for 1 lb = 0.453592 kg and 1 gal = 0.00378541 m³ (1/264.172 m³).

Q2: What's the typical density of water in these units?
A: Water is about 8.345 lb/gal or 999.5 kg/m³ at room temperature.

Q3: When would I need this conversion?
A: When working with international standards, scientific literature, or equipment that uses different unit systems.

Q4: How accurate is this conversion?
A: The conversion is mathematically exact, though actual densities may vary slightly with temperature and pressure.

Q5: Can I convert kg/m³ back to lb/gal?
A: Yes, divide kg/m³ by 119.826 to get lb/gal.
