Common examples:
Metric horsepower — abbreviated as PS (from German: Pferdestärke, meaning "horse strength") — equals exactly 735.499 watts or 75 kilogram-force meters per second. It is the standard power unit for car and ship engines in Europe, Japan, India, and most of Asia. Car brands like BMW, Mercedes, Porsche, Audi, Volkswagen, Toyota, and Honda rate their engines in PS. PS is slightly smaller than mechanical horsepower — 1 PS = 0.9863 hp.
BTU/Hour (British Thermal Units per hour) measures how fast heat energy is transferred. One BTU is the heat needed to raise one pound of water by 1°F. BTU/h is used in the US HVAC industry for rating air conditioners, furnaces, and heat pumps. Converting PS to BTU/h is useful in engineering when calculating heat rejection from European car engines and designing cooling or ventilation systems.

Multiply PS by 2,509.64. Formula: BTU/h = PS × 2,509.64. Example: 100 PS × 2,509.64 = 250,964 BTU/h.
1 PS = 2,509.64 BTU/hour. This is because 1 PS = 735.499 W, and 1 W = 3.41214 BTU/h, so 735.499 × 3.41214 = 2,509.64 BTU/h.
100 PS = 250,963.59 BTU/h. Formula: 100 × 2,509.64 = 250,964 BTU/h. This is the thermal output of a typical small European car engine.
1 PS = 2,509.64 BTU/h while 1 mechanical hp = 2,544.43 BTU/h. The difference is about 34.79 BTU/h per unit — roughly 1.4% — because PS (735.5 W) is slightly smaller than mechanical hp (745.7 W).
200 PS = 501,927.18 BTU/h. Formula: 200 × 2,509.64 = 501,928 BTU/h. This is the thermal output of a performance car engine.
This conversion is used in automotive engineering when designing cooling and ventilation systems for garages and workshops servicing European vehicles. It is also used when comparing engine thermal output across metric (PS) and imperial (BTU/h) unit systems.
