During the early part of the twentieth century, the French introduced their own units of power – the poncelet, which was defined as being the power required to raise a mass of 100 kg against standard gravity with a velocity of 1 m/s, giving a value of 980.665 W. [16] [17] However, many other European countries defined their units of power ...

A number of different units (some only of historical interest) are shown and expressed in terms of the corresponding SI unit. Conversions between units in the metric system are defined by their prefixes (for example, 1 kilogram = 1000 grams, 1 milligram = 0.001 grams) and are thus not listed in this article.
Metric units are units based on the metre, gram or second and decimal (power of ten) multiples or sub-multiples of these. According to Schadow and McDonald, [1] metric units, in general, are those units "defined 'in the spirit' of the metric system, that emerged in late 18th century France and was rapidly adopted by scientists and engineers.
