About this conversion
This Koverts page converts grams (g) to milligrams (mg) — three orders of magnitude for pharmacy, toxicology, and fine powder dosing.
The gram is already small for kitchen use — but drugs and supplements often require milligram precision printed on labels.
The milligram is one thousandth of a gram — standard for active ingredients, pollutants, and trace minerals.
Typical uses
- Medication and supplement facts panels
- Environmental contaminant limits
- Jewelry and gem carat-related mass checks
Common reference values
- 1 g = 1,000 mg
