kW ⇄ bhp Power Converter
Use this quick calculator to convert kilowatts (kW) to brake horsepower (bhp), or convert bhp back to kW.
1 kW = 1.34102209 bhp
1 bhp = 0.745699872 kW
What is a kW to bhp calculator?
A kW bhp calculator converts one engine power unit into another. In automotive and mechanical contexts, power is commonly shown as either kilowatts (kW) or brake horsepower (bhp). Because manufacturers in different countries use different standards, a reliable converter helps you compare engines accurately.
If you are reviewing performance specs for cars, motorcycles, marine engines, generators, or industrial equipment, unit conversion prevents confusion and helps you make fair comparisons.
kW vs bhp: understanding the difference
Kilowatts (kW)
Kilowatt is an SI (metric) unit of power. It is widely used in Europe and many global technical documents. One kilowatt equals 1,000 watts.
Brake horsepower (bhp)
Brake horsepower measures engine output at the crankshaft before drivetrain losses. It is commonly used in vehicle marketing and enthusiast communities, especially in regions where horsepower ratings are standard.
Why both units still matter
- Vehicle spec sheets can list either kW or bhp depending on market.
- Import/export comparisons often require converting both ways.
- Tuning discussions and dyno reports may switch between units.
- Legal documentation or registration records may require specific units.
Exact conversion formulas
Use these formulas for precise power conversion:
- bhp = kW × 1.34102209
- kW = bhp × 0.745699872
For quick mental math, people often approximate 1 kW as 1.34 bhp and 1 bhp as 0.746 kW, but the calculator above uses the more precise constants.
Common kW and bhp conversion values
| kW | bhp (approx.) | Typical Context |
|---|---|---|
| 55 kW | 73.76 bhp | Small city cars |
| 75 kW | 100.58 bhp | Entry-level compact vehicles |
| 100 kW | 134.10 bhp | Mainstream family cars |
| 150 kW | 201.15 bhp | Sport sedans / performance trims |
| 200 kW | 268.20 bhp | High-performance applications |

Practical examples
Example 1: Convert 110 kW to bhp
110 × 1.34102209 = 147.51 bhp (rounded to 2 decimals)
Example 2: Convert 250 bhp to kW
250 × 0.745699872 = 186.42 kW (rounded to 2 decimals)
Frequently asked questions
Is bhp the same as hp?
They are closely related but not always identical across standards. In many automotive contexts, bhp is treated as engine horsepower measured at the crankshaft.
Why does my converted value differ slightly from another website?
Small differences come from rounding methods, decimal precision, or slightly different constants. This calculator uses consistent precision to reduce mismatch.
Can I use this for electric vehicles?
Yes. Electric motors are often rated in kW, but many comparisons still use horsepower equivalents, making kW-to-bhp conversion very useful.
Final thoughts
A good kW bhp converter removes guesswork when comparing engine output across regions and technical sources. Whether you are buying a vehicle, tuning performance, writing specifications, or just satisfying curiosity, converting between kW and bhp gives you a clearer picture of real-world power.
