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: BTU per hour (symbol: BTU/h) measures thermal power as British thermal units transferred per hour.
History: Developed for heating and cooling systems to measure rate of heat transfer in imperial units.
Current Use: Standard in United States for heating, ventilation, air conditioning (HVAC) system ratings and thermal power.
Examples: Home furnace: 80,000 BTU/h, air conditioner: 12,000-36,000 BTU/h, water heater: 40,000 BTU/h
