What is the abbreviation for gram?

The abbreviation for gram is widely recognized as a single letter “g.” This abbreviation is adopted internationally and is the standard symbol used in scientific and academic contexts to represent the unit of mass known as the gram.

To clarify the other abbreviations: “gm” is another common abbreviation used for gram, though it is less standard compared to just “g.” The abbreviation “gr” stands for grain, which is a different unit of measurement. “mg” stands for milligram, which is one-thousandth of a gram. Understanding these distinctions is essential to ensure accurate communication in measurements, especially in fields like science, medicine, and nutrition where precise quantities are crucial.
