About both units

From

Kilowatt

The kilowatt equals 1000 watts. Car engine outputs in metric countries are usually given in kW; 100 kW ≈ 136 PS. Home electric panels are sized in kW (typical European home: 15–25 kW peak).

Real-world: Small car: 80 kW. Performance car: 200+ kW. Home peak load: 3–10 kW. Heat pump: 5–15 kW.

Tips & common mistakes

Quick tips

1 kW = 1000 W = 1.34 hp = 1.36 PS.
Home electricity contracted capacity often 3–11 kW in EU.
Multiply kW × hours = kWh energy consumed.

Avoid these

Confusing kW with kWh — power vs energy.
Assuming all hp measurements are identical — PS differs by 1.4%.
Exceeding contracted kW limit trips home main breaker.
