How to estimate your energy use
If your annual meter reading is in cubic feet, multiply by 2.83 to convert to metres. You don''t need to do this if your meter reading is already in cubic metres. Multiply by 1.02264. Multiply by the ''calorific value'' (this will be shown on your gas bill). Divide by 3.6 to work out your kWh figure.
