The amount of time and power that each appliance is used varies significantly between households, so for the best results, adjust the usage for each appliance to most accurately reflect your personal usage.

Units of electricity:

One of the most common units of electrical power for appliances is the watt (W).

Other common units of power include kilowatts (kW), British thermal units (BTU), horsepower (hp), and tons.

Watts, kilowatts and kilowatt-hours:

Watts (W) is a unit of power used to quantify the rate of energy transfer.

It is defined as 1 joule per second. A kilowatt is a multiple of a watt.
