Professional Metric Horsepower (hp M / PS) to Boiler Horsepower (hp S) converter. 100% accurate for 2026 international steam plant audits and maritime scaling.
In the global industrial landscape of 2026, precision across diverse measurement systems is the cornerstone of engineering success. The Metric Horsepower (hp M)u2014widely known as PS (Pferdestu00e4rke)u2014is the standard unit for rating engine and turbine output in Europe, Asia, and South America. Conversely, the Boiler Horsepower (hp S) is a specialized unit used globally in the steam industry to quantify the evaporation capacity of large-scale boilers. Converting Metric Horsepower to Boiler Horsepower is a foundational task for 2026 maritime engineers and industrial plant managers who must translate engine performance data (PS) into the steam-producing metrics (hp S) required for 2026 thermal audits and high-capacity equipment specifications.
Metric Horsepower is defined as the power required to lift a 75-kilogram mass one meter vertically in one second. In 2026, this value is fixed at exactly 735.49875 Watts. It is the legal standard for technical documentation across much of the globe, used for everything from high-performance automotive engines to massive ship turbines. Because PS is the primary metric for mechanical work in international markets, it serves as the starting point for 2026 global industrial calculations.
Boiler Horsepower is a unique unit that measures the capacity of a boiler to deliver steam. In 2026, it is defined as the amount of energy required to evaporate 34.5 pounds of water per hour at 212u00b0F. One hp S is equivalent to approximately 9,809.5 Watts. In the context of 2026 industrial systems, Boiler Horsepower remains critical for sizing steam infrastructure in massive chemical plants and maritime vessels where steam is used for both propulsion and heating.
To convert Metric Horsepower to Boiler Horsepower, you use the ratio of their respective Watt values (735.49875 to 9,809.5). Use this high-precision 2026 formula for your technical reports:
At AiCalculo, our engine utilizes this high-precision 2026 constant to ensure that your steam plant designs, maritime audits, and international reports are 100% accurate, allowing for zero-error scaling between metric mechanical power and steam capacity.
| Metric HP (hp M / PS) | Boiler Horsepower (hp S) | Kilowatts (kW) Equivalent |
|---|---|---|
| 13.34 PS | 1.0 hp S | ~9.81 kW |
| 100.00 PS | 7.50 hp S | ~73.55 kW |
| 500.00 PS | 37.49 hp S | ~367.75 kW |
| 1,000.00 PS | 74.98 hp S | ~735.50 kW |
In 2026, many international vessels use turbines rated in **PS** to drive auxiliary steam systems. To determine if the on-board boilers (measured in **hp S**) can meet the thermal demand of the turbines, this conversion is foundational. AiCalculo provides the exact figures needed for these 2026 naval architecture specifications.
Engineers in 2026 designing the interconnection for a European-built mechanical motor (rated in **PS**) to a steam-driven manufacturing line (measured in **hp S**) use this identity. Our tool bridges this technical gap instantly, supporting the accuracy of 2026 global manufacturing research.
