How do I convert my usage to kilowatt hours (kWh)?

A natural gas meter measures the amount of gas consumed by all gas appliances in a premises. The gas is measured in cubic meters or cubic feet at the meter point. However, you'll be billed in kilowatt hours (kWh).​​

For commercial gas usage, a conversion formula is used to convert cubic meters or cubic feet into kWhs. This conversion formula has been approved by the Commission for Energy Regulation.​​

The conversion formula can vary nationwide, as it depends on the local temperature, pressure and calorific value of the gas on the day the conversion takes place.​
