quintal

quintal (an unofficial metric unit of mass equal to exactly 100 kg); quintal, Spanish hundredweight (a traditional unit of mass equivalent to 100 libras, or about 46 kg)

Borrowed from Medieval Latin quintāle (“various medieval hundredweights”), from Andalusian Arabic and Arabic قِنْطَار (qinṭār, “100 rottols”), from Classical Syriac ܩܰܢܛܺܝܪܳܐ (qanṭīrā) and ܩܰܢܛܺܝܢܳܪܳܐ (qanṭīnārā), from Byzantine Greek κεντηνάριον (kentēnárion), from Latin centēnārium (“100 Roman pounds”), from centēnī (“100 things”) + -ārius (“-ary”, forming related adjectives). Doublet of centenario.
