What is a Watt?

A watt (W) is the most basic unit of power in the International System of Units (SI) used to measure the rate at which energy is generated, consumed, or transferred.

One watt is equivalent to one joule per second. Therefore, if an electrical device has a power rating of one watt, it is consuming one joule of energy every second.

How does a watt compare to a kilowatt?

One kilowatt (kW) is equal to 1,000 watts. When discussing energy overtime, kilowatts are measured in kilowatt-hours (kWh) while watts are measured in watt-hours (Wh).
