PS
This unit (German: Pferdestärke = horse strength) is no longer a lawful unit, but is still commonly used in Europe, South America and Japan, especially by the automotive and motorcycle industry. It was adopted throughout continental Europe with designations equivalent to the English "horse power", but mathematically different from the British unit. It is defined by the Physikalisch-Technische Bundesanstalt (PTB)[1] in Braunschweig as exactly:
1 PS = 75 kp·m/s = 0.73549875 kW = 0.9863201652997627 hp (SAE)
