1. What is Gasoline Density?

Definition: Density is the mass of gasoline per unit volume, typically measured in kilograms per cubic meter (kg/m³).

Typical Range: Gasoline density is typically between 720-750 kg/m³ at standard temperature (15°C).

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density (kg/m³)
• \( m \) — Mass (kg)
• \( V \) — Volume (m³)

Explanation: The mass of gasoline is divided by its volume to calculate density.

3. Importance of Gasoline Density

Details: Density affects fuel efficiency, engine performance, and is used for quantity conversions in the petroleum industry.

4. Using the Calculator

Tips: Enter the mass in kilograms and volume in cubic meters. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why does gasoline density vary?
A: Density changes with temperature and gasoline composition (octane rating, additives).

Q2: How does temperature affect density?
A: Gasoline expands when heated (lower density) and contracts when cooled (higher density).

Q3: What's the density of regular vs premium gasoline?
A: Regular (87 octane) is typically 730-750 kg/m³, premium (91-93 octane) 720-740 kg/m³.

Q4: How do I convert kg/m³ to other units?
A: 1 kg/m³ = 0.001 g/cm³ = 0.0624 lb/ft³ = 0.1335 lb/US gallon.

Q5: Why is density important in fuel storage?
A: Density helps calculate storage capacity and is used for inventory management.
