Power Units
Watt (W) — SI unit of power. 1 W = 1 J/s.
Kilowatt (kW) — 1 kW = 1000 W. Common for electrical appliances and engines.
Megawatt (MW) — 1 MW = 1,000,000 W. Used for power plants.
Gigawatt (GW) — 1 GW = 1,000,000,000 W. Country-scale power generation.
Milliwatt (mW) — 1 mW = 0.001 W. Used in electronics and radio.
Horsepower (hp) — 1 hp = 745.7 W. Engine and motor ratings.
BTU/hr — 1 BTU/hr = 0.293 W. HVAC and heating systems.
Refrigeration ton — 1 ton = 12,000 BTU/hr = 3,517 W. Air conditioning capacity.
dBm — Logarithmic ratio to 1 mW. 0 dBm = 1 mW. Used in radio and telecommunications.
