What is Watt?

The watt is the SI unit of power, named after Scottish inventor James Watt. One watt equals one joule of energy per second. Household LED bulbs use about 7 to 12 watts, a microwave oven uses 500 to 1,000 watts, and a hair dryer uses about 1,200 watts. Electricity bills are based on watt-hours, the product of power consumption in watts and time of use.

What is Kilowatt?

The kilowatt equals 1,000 watts and is widely used for home and industrial electrical equipment. Air conditioners are rated at 2.2 to 7.1 kW, induction cooktops at 2 to 3 kW, and EV chargers at 3 to 6 kW for Level 2 or 50 to 150 kW for DC fast charging. Residential solar panel systems are also described in kilowatts, such as a 4 kW system.
