Convert Horsepower (hp) to Cheval-vapeur (cv)
Use this simple tool to convert mechanical horsepower to metric horsepower (cv/PS) instantly.
What is the difference between hp and cv?
Both hp (horsepower) and cv (cheval-vapeur) are units of power used to describe engine output, motor size, and mechanical performance. They are extremely close in value, but not exactly the same.
- hp usually refers to mechanical horsepower used in the U.S. and some technical contexts.
- cv is metric horsepower, commonly used in parts of Europe and Latin America (often shown as PS or CV).
- Because the units are slightly different, converting accurately matters for specs, imports, and engineering documents.
hp to cv conversion formula
To convert horsepower to cv, multiply by 1.013869665.
cv = hp × 1.013869665
Example: if a car is rated at 200 hp:
200 × 1.013869665 = 202.774 cv
Reverse formula (cv to hp)
If you ever need to convert in the other direction:
hp = cv × 0.986320071

When do you need an hp to cv calculator?
This conversion is useful in real-world situations such as:
- Comparing imported vehicle specs listed in different unit systems.
- Reading motorcycle, marine engine, or industrial motor datasheets.
- Preparing technical reports, registration paperwork, or insurance forms.
- Matching engine output values from regional listings and manufacturer brochures.
Accuracy notes
1) Unit naming can be confusing
Some listings use “hp” loosely, even when they actually mean metric horsepower. Always check the source if precision matters.
2) Rounding differences are normal
You may see small output differences between tools due to different decimal precision (for example, 202.77 vs 202.774 cv).
3) Include kW when needed
Many technical documents also include kilowatts. The calculator above displays kW too, which helps with international comparisons.
FAQ
Is cv the same as hp?
Not exactly. They are close but different units, with cv being slightly larger than mechanical hp.
Why does my vehicle show PS instead of cv?
PS (Pferdestärke) and cv are both metric horsepower units, commonly treated as equivalent in automotive contexts.
Can I use this for electric motors?
Yes, if the motor rating is expressed in mechanical horsepower and you need cv. For strict engineering work, confirm the original rating standard.
Bottom line
If you need fast and accurate horsepower conversion, this hp to cv calculator gives you instant results with clear precision. Enter the hp value, click calculate, and use the converted cv number for vehicle specs, motor sizing, and technical comparisons.
