1. What is a Gas to kWh Calculator?

Definition: This calculator converts gas usage from cubic meters (m³) to kilowatt-hours (kWh) using the calorific value of the gas.

Purpose: It helps consumers and professionals understand their gas consumption in terms of energy units (kWh) which is commonly used for billing and energy comparisons.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ E = \frac{V \times CV}{3.6} \]

Where:

\( E \) — Energy in kilowatt-hours (kWh)
\( V \) — Volume of gas in cubic meters (m³)
\( CV \) — Calorific value of gas in megajoules per cubic meter (MJ/m³)
\( 3.6 \) — Conversion factor from MJ to kWh

Explanation: The gas volume is multiplied by its energy content (calorific value) and divided by 3.6 to convert from MJ to kWh.

3. Importance of Gas to kWh Conversion

Details: Converting gas usage to kWh allows for direct comparison with electricity usage and helps understand energy consumption in standardized units.

4. Using the Calculator

Tips: Enter the gas volume in cubic meters and the calorific value (default 38 MJ/m³, typical for natural gas). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is calorific value?
A: It's a measure of the energy content in gas, typically between 38-42 MJ/m³ for natural gas.

Q2: Where can I find my gas volume?
A: This is usually shown on your gas meter or utility bill in cubic meters (m³).

Q3: Why divide by 3.6?
A: 1 kWh = 3.6 MJ, so we divide to convert from MJ to kWh.

Q4: Does this work for all gas types?
A: Yes, but you need the correct calorific value for your specific gas type.

Q5: How accurate is this calculation?
A: Very accurate when using correct values, but actual billing may include additional factors.
