> Several countries (e.g. France) use the word pound (livre) to mean 500g

Note that nobody I know below the age of 70 uses the "livre" unit in France. It's something you see pretty much only in old recipes

Cereal production is still expressed in “quintal/hectare” with quintal keeping its old meaning of 100 livres but using the metric ones so 100kg.
