The term carat has been borrowed from the Latin name of the carob tree, the Ceratonia siliqua.
The seeds of the fruit of that tree always weigh between 197 and 216 milligram.
Already in antiquity these seeds were used as a weight unit. Just at the beginning of the twentieth century the metrics carat was determined internationally on 0.2 grams.
