How to use this PS to BHP calculator

If you're comparing car specs from different countries, you've probably seen power listed in PS, HP, BHP, or kW. That can make side-by-side comparisons confusing. This calculator helps by converting PS to BHP instantly.

• Enter the engine output in PS.
• Click Convert to BHP.
• Read the converted BHP value and optional kW equivalent.
• Use Reset to clear and try another value.

PS to BHP conversion formula

The conversion is straightforward:

BHP = PS × 0.9863200706

Because 1 PS is slightly smaller than 1 mechanical horsepower, the BHP value is always a little lower than the PS value.

Example calculations

• 100 PS = 98.632 BHP
• 150 PS = 147.948 BHP
• 200 PS = 197.264 BHP
• 300 PS = 295.896 BHP

What is PS?

PS stands for Pferdestärke, a unit of power commonly used in Europe. It is often referred to as metric horsepower. Many German and European car manufacturers use PS in brochures, technical sheets, and marketing materials.

What is BHP?

BHP means brake horsepower. Historically, it refers to power measured at the engine's output shaft using a braking dynamometer. In everyday use, BHP is treated very similarly to mechanical horsepower (HP), especially in UK automotive content.

PS vs BHP vs HP vs kW

These units all describe power, but their scales differ slightly:

• 1 PS = 0.98632 BHP (approx.)
• 1 BHP = 1.01387 PS (approx.)
• 1 PS = 0.73550 kW
• 1 kW = 1.35962 PS

For most normal driving comparisons, the difference between PS and BHP is small. But if you are comparing tuning figures, dyno charts, or regulations, using the correct unit matters.

Why power numbers can look different online

If you see two websites listing different values for the same vehicle, it does not always mean one source is wrong. Differences may come from:

• Unit conversion (PS vs BHP vs HP vs kW)
• Rounding (e.g., 197.26 rounded to 197 or 198)
• Model year changes or regional variants
• Marketing figures versus certified test figures

FAQ

Is PS the same as BHP?

Not exactly. PS is slightly smaller than BHP. Multiply PS by 0.98632 to get BHP.

Can I use this for motorcycles and trucks too?

Yes. The conversion is purely mathematical and works for any engine output measured in PS.

How many decimal places should I use?

For general comparison, 1 to 2 decimal places is enough. For engineering work, use more precision.

Final takeaway

Converting PS to BHP is simple once you use the right factor. Bookmark this page and use the calculator any time you compare vehicle specs across regions. It saves time, avoids confusion, and helps you make cleaner apples-to-apples comparisons.
