1. What is Petrol/Gasoline Density?

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

Typical Range: Petrol/gasoline density typically ranges between 720-750 kg/m³ at standard temperature and pressure.

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 petrol is divided by its volume to calculate its density.

3. Importance of Density Calculation

Details: Knowing petrol density is crucial for fuel storage, transportation, energy content calculations, and quality control in petroleum industry.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What affects petrol density?
A: Temperature is the main factor - density decreases as temperature increases. Composition also affects density.

Q2: Why is density important for petrol?
A: Density affects fuel efficiency, engine performance, and is used to calculate energy content per volume.

Q3: How does temperature affect density?
A: Petrol density decreases by about 0.75 kg/m³ for every 1°C temperature increase.

Q4: What's the difference between density and specific gravity?
A: Specific gravity is density compared to water, while density is absolute mass per volume.

Q5: How accurate is this calculation?
A: The calculation is mathematically precise, but real-world density varies with temperature and composition.
