What is the abbreviation for "gram" commonly used in medication dosages?

The abbreviation for "gram" that is commonly used in medication dosages is "g." This single lowercase letter is recognized internationally as the standard symbol for grams, making it essential in healthcare communication to indicate weight. The use of "g" helps avoid confusion, as it is simple and easily understood in the context of dosing and medication management.

While "gm" may occasionally be seen, particularly in older texts, it is less preferred in modern medical practice, where "g" is the standard used. Other abbreviations like "gr" refer to grains, which is a different measurement altogether, and "ml" stands for milliliters, used for measuring volume, not weight. Thus, “g” is the most accurate and appropriate answer in this context.
