mg to cc conversion explained
Milligrams (mg) measure mass. Cubic centimeters (cc) measure volume, and in medical contexts cc is used as a synonym for milliliters. To convert mg to cc, you need a concentration, written as mg per mL.
How the conversion works
If a solution has concentration in mg/mL and you want a dose in mg:
Because , the same value works in cc.
Units and conversions
| Quantity | Common unit | Notes |
|---|---|---|
| Dose | mg | |
| Volume | cc, mL | |
| Concentration | mg/mL | Use the value from your label or chart |
Worked examples
-
Converting 500 mg at 50 mg/mL
Result: 10 cc.
-
Converting 2 cc at 100 mg/mL into mg
Result: 200 mg.
Tips and pitfalls
- Concentration drives everything. A different strength changes the volume for the same mg dose.
- Keep units consistent. If your concentration is mg/cc, treat it the same as mg/mL.
- Round based on your syringe or measuring device, not on the first intermediate step.
