Good to know
Mechanical horsepower = 550 ft·lbf/s = 745.7 W. Metric horsepower (PS) = 75 kgf·m/s = 735.5 W. Indian car brochures often quote PS or bhp; check which one before comparing.
Air conditioners: 1 ton of refrigeration = 12,000 BTU/h = 3.517 kW of cooling. A 1.5-ton AC removes about 5.3 kW of heat; its electrical input is lower (see its BEE star label).
Power is energy per time: a 2 kW geyser running 30 minutes uses 1 kWh (1 unit).
