For other uses of the words gram or gramme, see gram (disambiguation). The gram or gramme (Greek/Latin root grámma) symbol g, is a unit of mass. Originally defined as the mass of 1 cubic centimeter of water at 4°C but now taken as the one one-thousandth of the SI base unit kilogram, or 1×10−3 kg, a mass preserved by the International Bureau of Weights and Measures.
Examples All masses are approximate: History It was the base unit of mass in the original French metric system and the later centimetre-gram-second (CGS) system of units. Uses The gram is today the most widely used unit of measurement for non-liquid ingredients in cooking and grocery shopping worldwide. For food products that are typically sold in quantities far less than 1 kg, the unit price is normally given per 100 g. Most standards and legal requirements for nutrition labels on food products require relative contents to be stated per 100 g of the product, such that the resulting figure can also be read as a percentage.
