Which abbreviation is used to denote the gram unit?

• A. Gramme
• B. g/gm
• C. Grain
• D. Grams

Answer: (B)

The gram is the basic metric unit of mass, and its symbol is a lowercase g. This is the standard abbreviation used in science, medicine, and everyday measurements—so you’d write 5 g, 0.5 g, etc. Gramme is an older spelling and not the current abbreviation. Grain is a different unit of mass entirely (about 0.0648 g). Grams is just the plural form, not a symbol. The string g/gm isn’t the conventional way to denote the unit; while some historical texts might use gm, the official SI symbol is simply g.
