kW-PS converter

Convert kW to horsepower: Engine power

Convert engine power between kilowatts and horsepower:

• 1 hp = 0.73549875 kW (exactly according to DIN 66036)
• 1 kW = 1.35962 hp (rounded to 1.36)
• Metric horsepower: 1 hp = 75 kp-m/s
• US Horsepower (HP): 1 HP = 0.7457 kW (slightly more than PS)

Quick conversion:

• kW × 1.36 ≈ HP
• HP × 0.735 ≈ kW
• Or: PS ÷ 1.36 ≈ kW

Examples:

• 100 kW = 136 hp
• 150 hp = 110 kW
• 200 kW = 272 hp
• 75 hp = 55 kW

Car tax: Calculated according to kW in Germany. Registration certificate shows both values.

Historical: PS obsolete, but still commonly used. Officially only kW in the EU.
