In Europe, and other regions using the ISO 216 paper sizing system, the weight is expressed in grammes per square metre (g/m2 or usually just g) of the paper. Printing paper is generally between 60 g and 120 g. Anything heavier than 160 g is considered card. The weight of a ream therefore depends on the dimensions of the paper and its thickness.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What ISO sizing system does Europe use?
Ah, so.. ISO 216

In some societies, clothing may be used to indicate rank or status. In ancient Rome, for example, only senators could wear garments dyed with Tyrian purple. In traditional Hawaiian society, only high-ranking chiefs could wear feather cloaks and palaoa, or carved whale teeth. Under the Travancore Kingdom of Kerala, (India), lower caste women had to pay a tax for the right to cover their upper body. In China, before establishment of the republic, only the emperor could wear yellow. History provides many examples of elaborate sumptuary laws that regulated what people could wear. In societies without such laws, which includes most modern societies, social status is instead signaled by the purchase of rare or luxury items that are limited by cost to those with wealth or status. In addition, peer pressure influences clothing choice.

Ah, so.. clothing choice

For centuries, Jews worldwide have spoken the local or dominant languages of the regions they migrated to, often developing distinctive dialectal forms or branches that became independent languages. Yiddish is the Judo-German language developed by Ashkenazi Jews who migrated to Central Europe. Ladino is the Judo-Spanish language developed by Sephardic Jews who migrated to the Iberian peninsula. Due to many factors, including the impact of the Holocaust on European Jewry, the Jewish exodus from Arab and Muslim countries, and widespread emigration from other Jewish communities around the world, ancient and distinct Jewish languages of several communities, including Judo-Georgian, Judo-Arabic, Judo-Berber, Krymchak, Judo-Malayalam and many others, have largely fallen out of use.
