Common examples:
Metric horsepower — abbreviated as PS (from German: Pferdestärke, meaning "horse strength") — is the standard unit of engine power used in Europe, Japan, India, and most of Asia. One metric horsepower equals exactly 735.499 watts or 75 kilogram-force meters per second (75 kgf·m/s).
You will see PS on the spec sheets of European and Japanese car brands like BMW, Mercedes, Volkswagen, Toyota, and Honda. When you see "150 PS" on a car brochure, it means 150 metric horsepower — slightly less than 150 US mechanical horsepower (hp).
BTU/Hour (British Thermal Units per hour) is a unit of power measuring heat energy transfer rate. One BTU is the heat needed to raise one pound of water by 1°F. BTU/h is primarily used in US HVAC systems for rating air conditioners, furnaces, and boilers. It is rarely used for engine power ratings — that's where PS or hp come in. However, converting between them is useful when comparing energy systems across different measurement standards.

| Vehicle Type | Power (PS) | Power (BTU/h) |
|---|---|---|
| Small scooter (100cc) | 8 PS | 20,077 BTU/h |
| Standard motorcycle | 50 PS | 125,482 BTU/h |
| Small hatchback (Maruti Alto) | 67 PS | 168,146 BTU/h |
| Compact sedan (Honda City) | 121 PS | 303,665 BTU/h |
| Mid-size SUV | 200 PS | 501,926 BTU/h |

Multiply BTU/h by 0.00039846. Formula: PS = BTU/h × 0.00039846. Example: 25,096 BTU/h × 0.00039846 = 10 PS.
1 PS = 2,509.63 BTU/hour. Metric horsepower equals 735.499 watts.
Metric HP (PS) = 735.499 W. Mechanical HP (hp) = 745.7 W. They differ by about 1.4%. 1 mechanical hp = 1.0139 PS. A 100 PS car = 98.6 hp.
PS stands for Pferdestärke — German for "horse strength". It is the metric unit of power used in Europe, Japan, India, and most of Asia for rating vehicle engines.
No. 1 PS = 0.9863 hp and 1 hp = 1.0139 PS. They are very close but not equal. European car specs use PS while US specs use hp — always check which unit is being used when comparing vehicles.
100 PS = 250,963 BTU/hour. Formula: 100 × 2,509.63 = 250,963 BTU/h. This is roughly the power output of a typical small car engine.
