What is the abbreviation for "gram" in scientific contexts?

In scientific contexts, the standard abbreviation for "gram" is primarily represented by the letter "g." While "gm" is also recognized and used occasionally, particularly in certain educational and historical contexts, "g" is the internationally accepted symbol endorsed by organizations such as the International System of Units (SI).

Using "g" as the abbreviation helps maintain consistency and clarity in scientific communication. It's important to note that "gms" is not a standard abbreviation and therefore not appropriate in formal scientific writing. Similarly, while "gr" may be encountered in specific contexts, it is less common and not the preferred abbreviation in modern scientific usage. Thus, "g or gm" encompasses both acceptable forms, with "g" being the most widely adopted.
