cc to mg Calculator
Convert cubic centimeters (cc) to milligrams (mg) using substance density. Since 1 cc = 1 mL, this is equivalent to mL to grams multiplied by 1000. Commonly used in pharmaceutical dosing and laboratory work.
How to Convert cc to mg
- Note that 1 cc = 1 mL.
- Multiply the volume in cc by the density (g/cc) to get grams.
- Multiply grams by 1000 to convert to milligrams.
Formula
mg = cc × Density (g/cc) × 1000
Example Calculation
Convert 1 cc of water to mg:
Density of water = 1.0 g/cc
Mass = 1 cc × 1.0 g/cc × 1000 = 1000 mg
Substance Density Reference Table
| Substance | Density (g/cc) | 1 cc = mg |
|---|---|---|
| Water | 1 | 1000 mg |
| Milk (whole) | 1.03 | 1030 mg |
| Cooking Oil | 0.92 | 920 mg |
| Honey | 1.42 | 1420 mg |
| Gasoline | 0.75 | 750 mg |
Frequently Asked Questions
Is 1 cc equal to 1000 mg?
For water, yes. 1 cc of water = 1 gram = 1000 mg. For other substances, multiply the density (g/cc) by 1000 to find mg per cc.
How many mg are in 5 cc of a medication?
It depends on the concentration of the medication. If the solution has a density close to water (1 g/cc), then 5 cc ≈ 5000 mg of solution. The active ingredient amount depends on the concentration (mg/mL).
Is cc the same as mL?
Yes, 1 cc (cubic centimeter) = 1 mL (milliliter). They are identical units of volume used interchangeably in medicine and science.
Why do doctors use cc instead of mL?
Historically, cc was preferred in medicine to avoid confusion between mL and other abbreviations. Today, mL is more commonly used, but cc remains in practice.
How do I convert cc to mg for a specific drug?
For medications, check the concentration on the label (e.g., 10 mg/mL). Multiply cc by the concentration to get mg of active ingredient. This is different from the mass of the solution itself.
