About both units

From

Watt

W

The watt is the SI unit of power — 1 joule per second. Named after James Watt. Common examples: LED bulb 5–10 W, laptop 45–100 W, kettle 2000–3000 W, car engine 50,000+ W.

Real-world: LED bulb: 5–10 W. Laptop: 45 W. Kettle: 2200 W. Oven: 2000 W. Sun per m² on Earth: 1361 W/m².

Metric Horsepower

PS

Metric horsepower (PS in German, ch in French) equals 735.5 watts. It is the standard power unit in European car marketing — a "200 PS" car has 147 kW. Slightly smaller than mechanical horsepower (1.4%).

Real-world: VW Golf GTI: ~245 PS = 180 kW. BMW M3: ~480 PS = 353 kW.

Tips & common mistakes

Quick tips

  • 1 W = 1 J/s = 1 V × 1 A (for DC).
  • LED lighting: 10× more efficient than incandescent.
  • For home appliances, rating × hours used = kWh.

Avoid these

  • Confusing watts (power) with joules (energy).
  • Assuming "100 W bulb" for LED — old incandescent rating.
  • Mixing W with V or A — different quantities.
