"The standard initial measuring unit for establishing the rated motive power output is the kilowatt (kW);[citation needed] and in their official literature, the power rating may be published in either the kW, or the 'Pferdestärke' (PS, which is sometimes incorrectly referred to as 'metric horsepower'), or both, and may also include conversions to imperial units such as the horsepower (hp) or brake horsepower (bhp). (Conversions: one PS ˜ 735.5 watts (W), ˜ 0.98632 hp (SAE)). In case of conflict, the metric power figure of kilowatts (kW) will be stated as the primary figure of reference."

While the above is correct, why would Wikipedia not advise the reader of the true definition of a "Pferdestarke", or PS. The unit of power is defined as 75 kilogram(force)-meters/second. While this is clearly a bastard unit in the SI, the understanding is quantitative.

1 kilogram force is the force create by 1 kilogram mass acted upon by the standard sea level gravitational acceleration of 9.80665 meters/second^2. Thus 1 kilogram force is equal to 9.80665 Newtons, and one PS is equal to 75 * 9.80665 = 735.49875 watts.

My argument - if the reader is given the underlying information, then the reader is not left to wonder how the conversion value of 1 PS = 735.5 watts was derived.

My source - I have included a link to an on-line source documenting and corroborating my claim that the definition of PS is 75 kilogram force - meters / second. My personal knowledge is based on verbal hand-down from the European automotive industry.
