Gas Usage Calculation Formula:
| From: | To: |
Gas usage calculation is the process of determining how much gas you've consumed based on meter readings and converting this to kilowatt-hours (kWh), which is the standard unit for energy billing in the UK.
The calculator uses the British Gas formula:
Where:
Explanation: The conversion factor accounts for the calorific value of the gas and converts volume (cubic meters) to energy (kilowatt-hours).
Details: Accurate gas usage calculation helps you understand your energy consumption, verify billing accuracy, manage energy costs, and track your carbon footprint.
Tips: Enter your previous and current meter readings in cubic meters (m³). The default conversion factor of 11.363 kWh/m³ is standard for natural gas in the UK, but you can adjust it if needed.
Q1: Where can I find my gas meter readings?
A: Gas meters are typically located outside your property, in a meter box, or inside in a cupboard or under the stairs. The reading is displayed in cubic meters (m³).
Q2: Why is the conversion factor 11.363 kWh/m³?
A: This standard value accounts for the average calorific value of natural gas supplied in the UK. The actual factor may vary slightly depending on your location and gas supplier.
Q3: How often should I take meter readings?
A: It's recommended to take monthly readings to track your usage accurately and avoid estimated bills.
Q4: What if my meter measures in cubic feet instead of cubic meters?
A: If your meter measures in cubic feet, you'll need to convert to cubic meters first (1 m³ = 35.315 ft³) before using this calculator.
Q5: Does this calculation work for all gas suppliers?
A: While the formula is standard, conversion factors may vary slightly between suppliers. Always check with your specific provider for their exact conversion factor.
