How do you differentiate kilowatt and kilowatt hour?
The kW stands for kilowatt, and one kW is equal to 1000 watts. It is used for measuring the power utilised by small devices like a bulb, cooler, fan, etc. Whereas, the kWh stands for a kilowatt hour. The kWh measures the energy utilises by the electrical equipment over a given period.
How do you calculate kilowatt hours?
A kilowatt-hour, expressed as kWh or kW·h, is a measure of energy that is equivalent to 1,000 watts of power for a 1-hour time period. Thus, to convert watts to kilowatt-hours, multiply the power in watts by the number of hours, then divide by 1,000. For example: let’s find the kWh of 1,500 watts for 2.5 hours.
