Horsepower to Metric Horsepower Converter

The horsepower-to-metric horsepower conversion is widely used across power measurement. Horsepower was coined by James Watt around 1783 to market steam engines by comparing them with the draft horses they replaced. One hp equals 550 foot-pounds per second. The metric horsepower has its own rich history: metric horsepower (ps, from german "pferdestarke") was defined as the power to raise 75 kg one meter in one second. Understanding both units and how they relate to each other is essential for professionals in automotive engineering, electrical systems, and renewable energy.

In practice, this conversion comes up frequently when reading appliance power ratings. For example, 1 hp = 1.01387 PS, 10 hp = 10.1387 PS, and 100 hp = 101.387 PS. A typical family car produces 120 to 200 hp. Similarly, a hot hatch typically delivers around 200 ps. Having an instant converter saves time and eliminates the risk of manual calculation errors, especially when precision matters.

To convert back from metric horsepower to horsepower, remember that 1 PS = 0.98632 hp. The horsepower is primarily used for car and motorcycle engines, boat motors, and power tools in the US, while the metric horsepower is the preferred unit for European and Japanese car engine ratings.
