How electricity is measured
A kilowatt-hour (kWh) is the amount of electricity produced or consumed in one hour.
In Australia, the typical daily usage of a common household is around 17,000 watt-hours of power. To calculate this from watts to kWh, it would equal around 17 kilowatt-hours.
= 1 watt
A 40 W lightbulb uses 40 watts of electricity.
= 1000 watts
