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.
Calories per second (cal/s)
Definition
Calories per second (cal/s) is a unit of power equal to approximately 4.187 watts. It represents the rate of energy transfer measured in thermochemical calories.
History
The calorie was defined in the 19th century as the amount of heat needed to raise one gram of water by one degree Celsius. Calories per second emerged as a power unit in thermodynamic calculations.
Current use
Calories per second is used in thermodynamics, chemical engineering, and metabolic studies to express rates of heat transfer and energy expenditure. It appears in scientific literature and specialized engineering calculations.
