Rechenweg Schritt fĂźr Schritt
- Schritt 1: 150 hp in die Basiseinheit (W) umrechnen: 150 Ă 745,699871582 = 111.854,980737 W.
- Schritt 2: Basiseinheit (Watt) in Kilowatt umrechnen: 111.854,980737 á 1.000 = 111,854981 kW.
- Direkter Faktor: 1 hp = 0,74569987 kW.
Wichtige Umrechnungsfaktoren
Mechanische Horsepower (hp): Britisch-amerikanische Horsepower (550 ft¡lbf/s)
hp to kW formula
Kurz gesagt: 1 hp = 0,74569987 kW, so multiply by 0,74569987: kW = hp Ă 0,74569987. Going back: hp = kW Ă 1,3410221.
How to convert mechanische Horsepower to Kilowatt
One mechanical horsepower is 550 ft¡lbf/s, exactly 745.69987158 W. Multiply horsepower by 0.7457 to get kilowatts. If the figure is metric horsepower (PS, CV, ch), multiply by 0.7355 instead; the converter's unit list includes both.
1. hp â kW
Multiply the number of mechanische Horsepower by the conversion factor:
Example: 150 hp Ă 0,74569987 = 111,85 kW.
2. kW â hp
To go back, divide by the same factor, or multiply by its reciprocal, 1,3410221:
Example: 111,85 kW á 0,74569987 = 150 hp.
Mental math: take off a quarter
Subtract a quarter of the horsepower. The estimate is about 0.6% high:
200 hp: 200 â 50 = 150 kW (exact: 149.14 kW).
