Energy Conversion Formula:
From: | To: |
Definition: This calculator converts gas meter readings (in cubic meters) to energy units (kilowatt-hours) using calorific value and conversion factors.
Purpose: It helps consumers and businesses understand their gas consumption in energy terms for billing and comparison purposes.
The calculator uses the formula:
Where:
Explanation: The formula converts the physical volume of gas to its energy equivalent by considering the gas quality (CV) and standard conditions (CF).
Details: Energy companies bill gas in kWh rather than volume because energy content varies. This conversion ensures fair billing regardless of gas quality.
Tips: Enter the gas volume from your meter (m³), calorific value (default 38.5 MJ/m³), and conversion factor (default 1.02264). All values must be > 0.
Q1: Where do I find the calorific value?
A: Your gas supplier provides this value, typically between 38-42 MJ/m³. It's often shown on your bill.
Q2: Why is the conversion factor needed?
A: It adjusts for temperature and pressure differences between your meter and standard conditions.
Q3: Is the conversion factor always the same?
A: It varies slightly by region and over time. Check with your local gas authority for current values.
Q4: How accurate is this calculation?
A: Very accurate when using correct CV and CF values from your supplier.
Q5: Can I use this for different gas types?
A: This is designed for natural gas. Other gases may require different CV values.
