cc to ml Converter
Convert cc to ml instantly: 1 cc = 1 ml exactly, by definition. This free cc to ml conversion calculator also converts milliliters back to cc, plus liters, teaspoons, tablespoons, fluid ounces, cups and medical drops, with a syringe dosing guide below.

How many ml in a cc?
There is exactly 1 ml in 1 cc. A cubic centimeter (cc) is the volume of a 1 cm cube, and the milliliter was defined to match it, so the cc to ml conversion factor is 1. Converting is trivial: keep the same number. 5 cc = 5 ml, 10 cc = 10 ml, 0.5 cc = 0.5 ml. The same holds in reverse for ml to cc conversion: 30 ml = 30 cc.

Syringe dosing: common cc to ml doses
Standard syringe sizes and what each marking means in ml. For unit conversion reference only, not medical advice.
| Syringe marking | Milliliters | Typical use |
|---|---|---|
| 0.5 cc | 0.5 ml | Small insulin or allergy doses |
| 1 cc | 1 ml | 1 ml syringe, common injections |
| 2.5 cc | 2.5 ml | Half teaspoon of oral liquid |
| 3 cc | 3 ml | Standard 3 ml syringe |
| 5 cc | 5 ml | One teaspoon of oral medicine |
| 10 cc | 10 ml | Two teaspoons, larger doses |
| 20 cc | 20 ml | Irrigation and feeding syringes |
Always follow the dosing instructions from your prescriber or pharmacist. This table converts units only.
cc vs ml: when to use which
- Medicine and syringes: both appear. Older syringes say cc, newer labels say ml. The amount is identical, so read either scale the same way.
- Science and nutrition: ml (or mL) is the standard. Lab reports and food labels use milliliters.
- Engines: cc is the convention. A 150 cc motorcycle engine displaces 150 cubic centimeters, which is exactly 150 ml of volume.
- Writing safety: many hospitals now write ml instead of cc because a handwritten cc can be misread. The volume does not change, only the label.
cc to ml FAQs
Is 1 cc equal to 1 ml?
Yes. 1 cc equals exactly 1 ml. The units are identical by definition: 1 cubic centimeter (cc) is defined as exactly 1 milliliter (ml), so the conversion factor is 1 and no calculation is needed. To convert cc to ml, keep the same number: 5 cc = 5 ml, 10 cc = 10 ml, and 100 cc = 100 ml.
What does cc stand for?
Cc stands for cubic centimeter, the volume of a cube measuring 1 cm on each side. Because 1 liter is defined as 1 cubic decimeter (1000 cubic centimeters), 1 cc works out to exactly 1 milliliter. The lowercase spelling cc is a long-standing convention; the SI symbol for cubic centimeter is cm3.
How many ml is 5 cc on a syringe?
5 cc is exactly 5 ml. Syringes marked in cc and syringes marked in ml measure the same thing, so a dose drawn to the 5 cc line is a 5 ml dose. Other common syringe readings convert the same way: 0.5 cc = 0.5 ml, 1 cc = 1 ml, 2.5 cc = 2.5 ml, and 10 cc = 10 ml.
Why do doctors and nurses say cc instead of ml?
It is mostly tradition. Syringes were historically graduated in cc, and medical training kept the term alive even after milliliters became the standard label. Clinically the two are interchangeable: a prescription for 2 cc of a liquid medication is a prescription for 2 ml. Modern safety guidance often prefers ml in writing because cc can be misread in handwriting, but the amount is identical.
How many cc are in a teaspoon?
1 US teaspoon equals 4.92892 cc (exactly 4.92892159375 ml). So 1 cc is about 0.202884 of a US teaspoon. A metric teaspoon, used in many recipes outside the US, is exactly 5 cc.
How many cc are in a tablespoon?
1 US tablespoon equals 14.78676 cc (exactly 14.78676478125 ml), which is 3 US teaspoons. A metric tablespoon is exactly 15 cc. For example, 15 cc converts to about 1.01442 US tablespoons.
How many cc are in a fluid ounce?
1 US fluid ounce equals 29.57353 cc (exactly 29.5735295625 ml), which is 2 US tablespoons. For example, 30 cc converts to about 1.01442 US fluid ounces. An imperial fluid ounce, used in the UK, is slightly smaller at 28.41306 ml.
How many cc are in a cup?
1 US cup equals 236.58824 cc (exactly 236.5882365 ml), which is 8 US fluid ounces. For example, 250 cc converts to about 1.05669 US cups. An imperial cup is 284.130625 ml.
How many cc are in a liter?
There are exactly 1000 cc in 1 liter, because 1 liter is defined as 1000 milliliters. So 500 cc = 0.5 liters and 250 cc = 0.25 liters.
How many drops are in 1 cc?
Under the standard medical assumption of 20 drops per milliliter, 1 cc equals 20 drops. So 0.5 cc is about 10 drops and 2.5 cc is about 50 drops. Real drop size varies with the dropper and the liquid, so this is an estimate, not a dosing rule.
Is a cc the same in motorcycle engines as in medicine?
Yes, the unit is the same. Engine displacement in cc (for example, a 150 cc motorcycle engine) means 150 cubic centimeters of cylinder volume, which is exactly 150 ml. The medical cc and the engine cc are both cubic centimeters; only the context differs.
How do I convert ml back to cc?
Use the same number in reverse, because the conversion factor is 1 in both directions. 30 ml = 30 cc, 2.5 ml = 2.5 cc, and 0.5 ml = 0.5 cc. Type the value into the converter above and swap the direction to convert ml to cc.
What is the difference between cc and mL?
There is no difference in volume: 1 cc = 1 ml exactly. The difference is only in naming and convention. Cc (cubic centimeter) comes from length-based volume, while ml (milliliter) comes from the liter-based metric system. Medicine traditionally says cc, science and nutrition labels usually say ml.
Can I use a 1 cc syringe to measure 1 ml of medicine?
Yes. A 1 cc syringe and a 1 ml syringe hold exactly the same volume. Fill to the 1 mark and you have measured 1 ml. The same applies at every size: a 5 cc syringe measures 5 ml and a 10 cc syringe measures 10 ml. Always follow your prescriber's dosing instructions; the converter above is for unit conversion only, not medical advice.
