At the close of the 19th century, a variety of horsepower standards based on local standards of length and weight existed in German-speaking areas¹, but all had values near that of the metric horsepower, 75 meter kilograms-force per second:
|Country||horsepower in local units||in meter
|Saxony||530 Fuss Pfund per second||75.045|
|Wurtemberg||525 Fuss Pfund per second||75.240|
|Prussia||480 Fuss Pfund per second||75.325|
|Hanover||516 Fuss Pfund per second||75.361|
|Austria||430 Fuss Pfund per second||76.119|
In the 20th century, the unit was equivalent to the metric horsepower, 735.498 75 watts.
In 1971, the European Economic Community directed that use of this unit cease by 31 December 1977.²
