: a metric unit of mass equal to 1⁄1000 kilogram and nearly equal to the mass of one cubic centimeter of water at its maximum density—abbreviation gram
: the weight of a gram under standard gravity
Variants of GRAM
gramor chiefly Britishgramme\ˈgram\
Unit of mass or weight used especially in the centimetre-gram-second (CGS) system of measurement. One gram is equal to 0.001 kg, about 0.035 oz, or 15.43 grains. The gram is very nearly equal to the mass of 1 cc of pure water at its maximum density. The gram of force is equal to the weight of a gram of mass under standard gravity. For greater precision, the mass may be weighed at a point at which the acceleration due to gravity is 980.655 cm/sec2. See alsogravitation; metric system.
