Which abbreviation represents the gram?

Which abbreviation represents the gram?

• A. kg
• B. g, gm
• C. L
• D. mg

Answer: (B)

Mass is measured in grams in the metric system, and the standard abbreviation for a gram is g. In some contexts you’ll also see gm used as an informal or older spelling, so both g and gm denote the gram. The other units shown represent different quantities: kilogram (kg) is 1000 grams, liter (L) is a unit of volume, and milligram (mg) is 1/1000 of a gram. So the abbreviation that represents the gram—and commonly used forms of it—are g and gm.
