1. What is kWh to m³ Gas Conversion?

Definition: This calculator converts energy in kilowatt-hours (kWh) to gas volume in cubic meters (m³) using calorific value and conversion factors.

Purpose: It helps energy consumers and professionals convert between energy units used in billing and actual gas volume measurements.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V_{gas} \) — Gas volume (cubic meters)
• \( E_{kWh} \) — Energy (kilowatt-hours)
• \( CV \) — Calorific value (MJ/m³)
• \( CF \) — Conversion factor (dimensionless)

Explanation: The energy in kWh is converted to MJ (by multiplying by 3.6), then divided by the product of calorific value and conversion factor.

3. Importance of Energy to Volume Conversion

Details: Gas is billed by energy content (kWh) but measured by volume (m³). This conversion helps understand actual gas usage and compare different gas supplies.

4. Using the Calculator

Tips: Enter energy in kWh, calorific value (default 38.5 MJ/m³), and conversion factor (default 1.02264). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is 3.6 used in the formula?
A: It converts kWh to MJ (1 kWh = 3.6 MJ) since calorific value is in MJ/m³.

Q2: What's a typical calorific value?
A: Natural gas typically ranges 38-41 MJ/m³, with 38.5 MJ/m³ being a common average.

Q3: What is the conversion factor for?
A: It accounts for temperature and pressure differences between billing conditions and actual usage.

Q4: Where can I find my gas CV and CF?
A: These values are usually provided by your gas supplier on bills or their website.

Q5: Is this calculation reversible?
A: Yes, to convert m³ to kWh, use: \( E_{kWh} = \frac{V_{gas} \times CV \times CF}{3.6} \)
