Quintal

The quintal or centner is a historical unit of mass in many countries which is usually defined as 100 base units of either pounds or kilograms. In British English, it referred to the hundredweight; in American English, it formerly referred to an uncommon measure of 100 kilograms.

Both terms share their roots in the Classical Latin centenarius, meaning hundredlike, but the quintal has a convoluted etymology: It became Late Latin centenarium pondus, then in succession, Byzantine Greek κεντηνάριον (kentenarion) and Arabic qintar قنطار. The qintar was reimported to Europe by traders during the Middle Ages, where it became Medieval Latin quintale, and finally Old French quintal before passing into the English language from French.

The word centner, on the other hand, is simply a Germanicized form of its original Latin name centenarius.

Languages drawing its cognate name for the weight from Arabic qintar include Spanish quintal, French quintal, Italian quintale, Portuguese quintal, Ukrainian квінтал (kvintal), Esperanto kvintalo. Languages taking their cognates from Germanicized centner include German Zentner, Lithuanian centneris, Swedish centner, Polish cetnar, Russian центнер (tsentner), Estonian tsentner, and Spanish centena.

Many European languages have come to translate both the imperial and American hundredweight as their cognate form of quintal or centner.
