British manufacturers often intermix metric horsepower and mechanical horsepower depending on the origin of the engine in question.DIN 66036 defines one metric horsepower as the power to raise a mass of 75 kilograms against the Earth's gravitational force over a distance of one metre in one second: 75&nbsp;kg × 9.80665&nbsp;m/s2 × 1&nbsp;m / 1&nbsp;s = 75&nbsp;kgf⋅m/s = 1&nbsp;PS. This is equivalent to 735.49875&nbsp;W, or 98.6% of an imperial mechanical horsepower. In 1972, the PS was replaced by the kilowatt as the official power-measuring unit in EEC directivessource: <a href="https://en.wikipedia.org/wiki/Horsepower#:~:text=DIN%2066036%20defines%20one%20metric,of%20an%20imperial%20mechanical%20horsepower.">Wikipedia&nbsp;</a>
