Electricity consumption is measured in kilowatt-hours and
will be stated on your meter and previous bills.
Each of the electric appliances in your home should have a ‘power rating’ – measured in kilowatts – that gives you an idea of how energy-intensive it is. A Kilowatt-Hour (kWh) therefore measures the amount of kilowatts this appliance uses in one hour.
A 60-watt light bulb consumes 0.06 kWh of energy per hour. So if you leave your lamp on for two hours, it “costs” you: 0.06 x 2 = 0.12 kWh.
Gas units are not stated in Kilowatt-Hours on your meter and therefore need to be converted. You will either have a metric or imperial meter and the method used for converting will be different for each.
Below is how you can simply convert to kWh:
Imperial Conversion - if your meter measures cubic feet: multiply your number of units by 31.5936
Metric Conversion - if your meter measures cubic meters: multiply your number of units by 11.1638
