Unit Converters

mg to cc (Mass to Volume by Concentration)

Convert milligrams to cubic centimeters using the concentration of the substance. One cc is exactly one milliliter, and presets cover common medication suspensions and household liquids.

How to use
  1. Enter a mass in milligrams.
  2. Choose a preset or enter the concentration.
  3. Convert back from cc to mg when you need to.

How it's calculated

cc = mg ÷ C

mg = mass in milligrams, cc = volume in cubic centimetres, C = concentration in mg/cc. Reverse: mg = cc × C.

Common questions

Is a cc the same as a mL?

Yes, exactly. One cubic centimeter equals one milliliter, so the two units are interchangeable.

Why do I need the concentration?

Milligrams measure mass and cc measures volume. The concentration tells the calculator how much mass sits in each cc.
