kWh

Kilowatt-Hour

The standard unit of electricity consumption — one 1000W appliance running for one hour.

A kilowatt-hour is the standard billing unit of electricity in Australia. One kWh equals 1000 watts of power consumed for one hour. The "annual energy use" figure on every appliance label is expressed in kWh per year. Multiplying that figure by your electricity rate (typically 25 to 40 cents per kWh in 2026) gives an estimated annual running cost.
