Start with the general units guide, then use the fan, AC or fridge guide for equipment that changes its power during use.
Learn to calculate appliance unitsUse a number you can check
For a steady 60 W appliance used for 8 hours a day over 30 days: 60 × 8 × 30 ÷ 1,000 = 14.4 kWh. That is 14.4 electricity units. A fridge or inverter AC needs a different approach because its power changes during operation.
Fan comparisons · AC operating estimates · Fridge labels and measurements
These are educational estimates. Examples are labelled assumptions, not household measurements or guaranteed savings. Source years and exclusions are explained in the methodology. Fixed charges, taxes and tariff blocks can make your actual bill change differently.
