Professional Metric Horsepower (hp M / PS) to Electrical Horsepower (hp E) converter. 100% accurate for 2026 international motor audits, electrical grid scaling, and global power mapping.
In the highly standardized electrical and mechanical sectors of 2026, precision in unit conversion is the bedrock of industrial efficiency. The Metric Horsepower (hp M)u2014commonly known as PS (Pferdestu00e4rke)u2014is the definitive unit for rating engine output in Europe, Asia, and South America. Conversely, Electrical Horsepower (hp E) is a fixed unit used specifically in the electrical industry to rate large-scale motors and generators, primarily in North American and international electrical codes. Converting Metric Horsepower to Electrical Horsepower is a foundational task for 2026 electrical engineers and systems designers who must translate mechanical engine performance (PS) into the standardized electrical units (hp E) required for 2026 motor specifications and power grid integration.
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 automotive performance to industrial turbines. Because PS is based on metric mass and distance, it serves as the stable baseline for 2026 mechanical performance tracking in metric-compliant regions.
Electrical Horsepower is a specialized definition used in electrical engineering to simplify the relationship between horsepower and the Watt. In 2026, one Electrical Horsepower is defined as exactly 746 Watts. This integer-based unit is the global benchmark for rating the output of electric motors, as it aligns perfectly with electrical calculations involving voltage and amperage. Understanding the difference between a mechanical PS rating and an electrical hp E rating is critical for ensuring that an electric motor is correctly sized to replace a combustion engine of a given PS rating.
The relationship between Metric Horsepower and Electrical Horsepower is a fixed physical constant based on their respective Watt identities. To convert Metric Horsepower to Electrical Horsepower, you multiply the hp (M) value by approximately 0.9859:
