Understanding Watts and Power Conversion

What is a Watt?

A watt (W) is the SI unit of power, measuring the rate of energy transfer. One watt equals one joule of energy per second. It's commonly used to measure electrical and mechanical power output.

Common Applications

Watts are used to measure power consumption in household appliances, light bulbs, solar panels, and electronic devices. For example, a typical LED bulb might use 10W, while a microwave might use 1000W (1kW).
