3. SG in Science and Medicine
(a) Specific Gravity (Physics, Chemistry, Medical Labs)
In science, SG stands for Specific Gravity — a dimensionless measurement that compares the density of a substance to the density of pure water (at 4°C). A specific gravity of 1.000 means the substance has the same density as water. Values above 1 indicate higher density; values below 1 indicate lower density.

In medical and surgical contexts, SG stands for Sleeve Gastrectomy, a popular bariatric (weight-loss) surgical procedure. During the operation, approximately 75–80% of the stomach is removed, leaving a narrow, sleeve-shaped tube. This limits food intake and reduces hunger hormones.

The title appears in official documents, advisories, and policy briefs. For example, advisories on smoking, COVID-19, mental health, and nutrition have historically been issued under the Surgeon General’s authority.
(b) Secretary General

6. SG in Sports

- SG: Approach-the-Green — iron play accuracy
- SG: Around-the-Green — short game performance

Golf analysts, commentators, and fantasy sports players regularly reference SG statistics to evaluate player performance. This meaning is essential for anyone following professional golf.

In basketball, SG stands for Shooting Guard — the player position typically responsible for perimeter shooting and scoring. It is one of the five standard positions alongside Point Guard (PG), Small Forward (SF), Power Forward (PF), and Center (C).

Special Grade entities are considered the most powerful and dangerous, making this abbreviation extremely common in fan communities, Discord servers, and gaming adaptations of the franchise.
(b) Server/Gaming Communities
In online gaming, SG can refer to a Singapore-based server. Players from Southeast Asia use “SG” to indicate they play on Singapore servers for lower latency and better connection performance. It is also occasionally used as a shorthand for “Super Good” or “Skilled Gamer” in competitive gaming circles.
8. SG in Business and Finance
In business accounting, SG&A stands for Selling, General & Administrative expenses — a major line item on income statements representing all non-production operating costs.
