A cubic centimetre and a millilitre are the same volume, so the number does not change. Doctors and syringes often say “cc”; recipes and bottles say “mL”.
How to use the cc to mL Converter
- Type the number of cubic centimetres into the Cubic centimetres field. Decimals such as 2.5 are fine.
- Read the answer in Millilitres – it updates as you type, with no button to press.
- To convert the other way, type into Millilitres and the cubic centimetres are recalculated.
- Press Copy results to copy both values with the page title, or Copy link to share this exact conversion.
This page converts only cm³ (cc) ⇄ mL. Need a different unit? Use the general volume converter, where you can choose any “from” and “to” unit.
How it works
Both units measure volume, so they are always in the same ratio: one cubic centimetre equals 1 millilitres. The calculator multiplies the number of cubic centimetres you type by 1 to give millilitres, and when you type into the millilitres field it divides by the same factor to give cubic centimetres. Because the ratio never changes, doubling the cubic centimetres always doubles the millilitres. Results are calculated at full precision and rounded only for display (up to eight decimal places, with very large or small values shown in scientific notation).
How to convert cubic centimetres to millilitres
- Write down the value in cubic centimetres, for example 5 cm³ (cc).
- Multiply by the conversion factor 1 (because 1 cubic centimetre = 1 mL).
- 5 × 1 = 5 mL.
- To go back from millilitres to cubic centimetres, divide by 1 – or multiply by 1.

What is a cubic centimetre?
A cubic centimetre (cc) equals one millilitre. Engine displacement and syringe volumes are commonly given in cc.
What is a millilitre?
A millilitre is one thousandth of a litre and exactly one cubic centimetre. Medicines, cosmetics, drinks and kitchen measures are labelled in mL.
Common mistakes to avoid
Mixing u.s. and uk gallons, pints and fluid ounces, assuming a cup is always 250 ml, and treating volume and weight as interchangeable for anything except water.

Results — Millilitres = 5 mL.
Frequently asked questions
Is 1 cc the same as 1 mL?
Yes, exactly.
How many cc in a teaspoon?
About 4.93 cc.
How many millilitres are in one cubic centimetre?
1 cm³ (cc) = 1 mL.
How many cubic centimetres are in one millilitre?
1 mL = 1 cm³ (cc).
How do I convert cubic centimetres to millilitres?
Multiply the number of cubic centimetres by 1. For example, 5 cm³ (cc) × 1 = 5 mL.
How do I convert millilitres back to cubic centimetres?
Divide by 1 (or multiply by 1), or simply type the value into the millilitres field above.
What is 10 cm³ (cc) in millilitres?
10 cm³ (cc) = 10 mL.
What is 100 cm³ (cc) in millilitres?
100 cm³ (cc) = 100 mL.
Is this conversion exact?
Yes. The factor comes from the official definitions of both units (NIST and the SI), so the only difference you may see is rounding in the last displayed digit.
Can I convert to other units on this page?
This page converts only between cubic centimetres and millilitres. To pick any volume unit, use the general volume converter linked under Related calculators.
What formula does the cc to mL Converter use?
1 cm³ (cc) = 1 mL.
