About BTU per Hour (BTU/hr)
An imperial unit of power (rate of heat transfer), equal to approximately 0.293 watts. BTU/hr is the dominant unit for US HVAC equipment sizing: air conditioner and heat pump capacity (a 24,000 BTU/hr unit is a "2-ton AC"), furnace output, water heater capacity, and heating/cooling load calculations per room. One "ton of refrigeration" = 12,000 BTU/hr ≈ 3.517 kW. Converting BTU/hr to watts is standard when US HVAC equipment is used in metric-labeled markets.
About Watt (W)
The SI unit of power, equal to one joule per second. Named after Scottish engineer James Watt, whose 18th-century steam-engine improvements made the unit conceptually possible. Watts are the universal electrical and mechanical power unit — lightbulb ratings (9W LED ≈ 60W incandescent equivalent), small-appliance input, audio equipment output (speakers, amplifiers), and solar panel output (~300–400 W peak per panel). Scientific and engineering literature quotes all power in watts.
