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 Kilowatt (kW)
A metric unit of power equal to 1,000 watts. Kilowatts are the practical unit for larger appliances and systems — electric kettles (1.5–3 kW), car EV motors (150–400 kW peak), home solar systems (5–10 kW), data centers, and industrial machinery. Utility-scale electricity is priced in kWh (kilowatt-hours), so the kilowatt is the natural rate unit for billing. Converting kW to horsepower (×1.341) is routine for internationally traded engines and motors.
