Question: 1 / 400

What is the abbreviation for "gram" used in measurement?

g

The abbreviation for "gram" used in measurement is "g." This single-letter abbreviation is the standard unit symbol for grams in the metric system, which is widely recognized and used in scientific and medical contexts. The use of "g" simplifies communication and avoids confusion, especially in contexts where precise measurements are critical, such as in pharmacology, nutrition, and laboratory settings.

Other abbreviations like "gm" are often used informally but are not the preferred standard. Though "gr" refers to grains, it is a different unit of measurement altogether, which adds to the importance of using "g" specifically for grams to avoid any misunderstanding.
