A quintal metric, also known simply as a "quintal," is a metric unit of mass or weight used in many countries around the world, especially in regions that follow the metric system. It is equal to 100 kilograms or 100,000 grams. The term "quintal" is derived from the Latin word "quintalis," which means "related to five."
1 quintal metric = 100 kilograms = 100,000 grams
Quintals are often used in agricultural and commercial contexts, particularly for measuring the weight of crops, grains, and other bulk materials. They provide a convenient way to express large quantities of goods. In some regions, quintals are still commonly used for trade and commerce, especially in agriculture, where it simplifies calculations and transactions involving significant quantities of produce.
