Watts (W)
Definition
A watt (W) is the SI unit of power, defined as one joule per second (1 W = 1 J/s). It measures the rate of energy transfer or conversion.
History
The watt was named after James Watt, the Scottish inventor who improved the steam engine in the 18th century. It was adopted as the SI unit of power in 1960 by the General Conference on Weights and Measures.
Current use
Watts are universally used to measure electrical power consumption (light bulbs, appliances), mechanical output, and energy transfer rates. Electricity bills, device ratings, and power plant capacities all reference watts.
Kilowatts (kW)
Definition
A kilowatt (kW) is a unit of power equal to 1,000 watts. It is commonly used to express moderate to large power outputs.
History
The kilowatt became widely used with the expansion of electrical power distribution in the late 19th and early 20th centuries. It provided a practical scale for describing household and industrial electricity usage.
Current use
Kilowatts are the standard unit for rating household appliances, electric vehicle motors, solar panel systems, and small to medium generators. Home electricity consumption is often measured in kilowatt-hours (kWh).
