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 is the standard unit of measurement in the metric system for mass and is widely recognized in medical settings. When prescribing or administering medications, healthcare providers often use this abbreviation to ensure clarity and avoid any potential confusion regarding dosages.

The abbreviation "gm," while it may be encountered, is not the preferred standard and can sometimes lead to misunderstandings or misinterpretations in clinical practice. The other options such as "gr" refers to grains, which is an older measure of weight not typically used in modern medication dosages, and "ml" represents milliliters, a unit of volume, which does not relate to mass. Hence, "g" is the most accurate and accepted abbreviation.
