Hard metrication which resulted in new products based on round metric quantities: for example A4 paper [a] replaced both foolscap and quarto paper; and in rugby union 5-, 10-, and 22-metre lines replaced the 5-, 10-, and 25-yard lines respectively.

The US customary system uses the short hundredweight of 100 lb and short ton of 2,000 lb. Where these systems most notably differ is in their units of volume.
Meanwhile, British scientists and technologists were at the forefront of the metrication movement – it was the British Association for the Advancement of Science that promoted the CGS system of units as a coherent system [77]: 109 and it was the British firm Johnson Matthey that was accepted by the CGPM in 1889 to cast the international ...

Gravitational metric system was a little-used variant of the metric system that normalised the acceleration due to gravity. Metre–tonne–second system of units was a variant of the metric system used in French and Russian industry between the First and Second World Wars. Between 1812 and 1839 France used a quasi-metric system: Mesures usuelles
