About Horsepower
Definition: Metric horsepower (symbol: PS) equals 735.5 watts, slightly different from mechanical horsepower used in imperial systems.
History: European standardization of horsepower using metric units, defined as 75 kilogram-force meters per second.
Current Use: Used in Europe and countries with metric systems for automotive and machinery power ratings.
Examples: European car specs: 90-300 PS, motorcycle: 15-180 PS, tractor: 50-400 PS, boat engine: 10-500 PS
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
