Common Contexts
- In economics or statistics, it refers to the share or importance of a sector or group.
- In physics or chemistry, it can mean specific gravity or relative density.
Collocations and Patterns

Usage Notes
"比重" is more formal and quantitative than just "比例" (ratio). It often implies importance or weight beyond mere numerical ratio. Avoid confusing it with "重量" which means physical weight. When used in social contexts, it highlights the significance or influence of a group within a population.
