CC to mL Converter — Cubic Centimetres to Millilitres
1 cc equals 1 mL exactly — convert cubic centimetres to millilitres (and back) along with litres, fluid ounces, teaspoons, tablespoons and US cups in one step.
Input unit
1 cc = 1 mL — identical units by SI definition

Input volume (cc = mL)
250 - 2
Millilitres (identical unit)
2501 cc = 1 mL exactly — same unit by SI definition.
How does this calculator work?
1 cc = 1 mL exactly — no conversion needed, just different names. To change to other units: 1,000 cc = 1 L; 1 cc ≈ 0.034 US fl oz; 1 cc ≈ 0.203 US tsp; 1 cc ≈ 0.068 US tbsp. All US cooking conversions are exact by US standards definition.
Formula
How this is calculated
Cubic centimetres (cc or cm³) and millilitres (mL) are the same unit of volume. This is not an approximation — it is an exact identity from the SI definition of the litre: 1 litre = 1 decimetre³ = 1,000 cm³ = 1,000 mL, which means 1 cm³ = 1 mL exactly. In everyday language, doctors and pharmacists prefer mL, while engineers, scientists and automotive contexts prefer cc or cm³ — but the numbers are always interchangeable.
For US customary cooking units, the relationships are defined by legal US measurement standards: 1 US fluid ounce = 29.5735 295 625 mL (exact); 1 US teaspoon = 1/6 fl oz = 4.9289 mL; 1 US tablespoon = 1/2 fl oz = 14.7868 mL; 1 US cup = 8 fl oz = 236.588 mL. These values are applied without rounding in this calculator.
Note that Imperial (UK) fluid ounces differ from US: 1 UK fl oz ≈ 28.413 mL. This converter uses US definitions throughout. If you need UK measures, use the general volume converter.
Frequently asked questions
Yes, exactly. 1 cubic centimetre (1 cc = 1 cm³) equals 1 millilitre (1 mL) by SI definition. The two units are used in different professional contexts but always denote exactly the same volume.
Since 1 cc = 1 mL and 1 US teaspoon = 4.929 mL, 5 cc ≈ 1.015 US teaspoons — very close to 1 teaspoon. Medically, a 5 mL / 5 cc dose is commonly treated as exactly 1 metric teaspoon (5 mL), which differs slightly from the US cooking teaspoon.
A US fluid ounce is 29.574 mL; a UK (Imperial) fluid ounce is 28.413 mL — about 4% larger. This calculator uses US fl oz. For UK / Imperial conversions, use the Volume Converter.
