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.
BTU per hour (BTU/h)
Definition
BTU per hour (BTU/h) is an imperial unit of power equal to approximately 0.293 watts. It measures the rate of thermal energy transfer.
History
The British Thermal Unit (BTU) was established in the 19th century to quantify heat energy. BTU/h emerged as the standard for heating and cooling system ratings, particularly in North America.
Current use
BTU/h is the standard unit for rating heating, ventilation, and air conditioning (HVAC) systems in the United States and Canada. Furnace output, air conditioner capacity, and water heater ratings are specified in BTU/h.
