What is the abbreviation for gram?

The abbreviation for gram is represented as "gm." This is a widely accepted standard across various fields, including medicine and nutrition, where clear communication of measurements is essential. Using "gm" as an abbreviation helps to avoid confusion, particularly when dealing with units of measure that may sound similar or resemble one another, such as grams and milligrams.

The other options present different abbreviations for other measurements or contexts. For example, "g" is often used as a general abbreviation for grams but is less specific and may lead to ambiguity in more complex calculations. "gr" stands for grains, which is a different unit of weight entirely, and "gms" is a less common pluralization that is not standardized. Therefore, "gm" is the most appropriate and widely recognized abbreviation for gram in medical and scientific contexts.
