About Watt
Definition: The watt (symbol: W) is the SI unit of power, equal to one joule per second or the rate of energy transfer.
History: Named after Scottish inventor James Watt in 1882. Standardized as SI unit to measure rate of energy consumption or production.
Current Use: Universal standard for electrical power ratings, mechanical power output, and energy transfer rates worldwide.
Examples: LED bulb: 10W, laptop: 65W, microwave: 1000W, hair dryer: 1500W, electric kettle: 2000W
About Per
Definition: Calorie per second (symbol: cal/s) measures thermal power as calories of heat energy transferred per second.
History: Thermal power measurement used in scientific applications and thermodynamic calculations.
Current Use: Used in thermodynamics, calorimetry, heat transfer studies, and scientific thermal power measurements.
Examples: Laboratory heating: 1-100 cal/s, calorimeter studies: 0.1-10 cal/s, thermal analysis: 0.01-1 cal/s
