Centimeters To Milliliters Converter Calculator

Last Updated: June 29, 2026

Calculate milliliters from cubic centimeters instantly, with liters, fluid ounces, teaspoons, tablespoons, and cups in US or UK units.

Centimeters to Milliliters Converter Calculator

A cubic centimeter (cc or cm³) and a milliliter measure the same volume, so the values match one to one.
Required: a volume in cubic centimeters (cc).
Enter the value you want to convert into milliliters.
Required: a volume in milliliters (mL).
Enter the value you want to convert into cubic centimeters.
Decimal places set the rounding for every result. The fluid ounce standard switches the ounce, teaspoon, tablespoon, and cup outputs between US and UK measures.

Centimeters to Milliliters Formula

In this conversion "centimeters" means cubic centimeters (cc or cm³), a unit of volume. A milliliter is defined as the volume of one cubic centimeter, so the two units are equal and the conversion factor is exactly 1.

To convert cubic centimeters to milliliters, multiply the cubic centimeter value by 1:

mL = cc * 1

To convert milliliters back to cubic centimeters, multiply the milliliter value by 1:

cc = mL * 1
  • cc: the volume in cubic centimeters (also written cm³)
  • mL: the volume in milliliters
  • 1: the conversion factor, because one cubic centimeter equals one milliliter exactly

The direction selector decides which way the conversion runs. Because the factor is 1, the number you enter is the same number you get back, only the unit label changes. The calculator also reports the volume in liters, fluid ounces, tablespoons, teaspoons, and cups so you can move from a metric measurement straight to the units on a measuring cup or syringe. The advanced options let you set the decimal places and switch the fluid ounce, teaspoon, tablespoon, and cup outputs between US and UK (imperial) measures.

Common cc to mL Volume Conversions

Because one cubic centimeter equals one milliliter, the first two columns are always identical. The remaining columns show the same volume in everyday cooking and dosing units, using US measures.

This second table relates milliliters to larger volume units, which helps when you scale a measurement up to liters or down to a single teaspoon.

Example Problems

Example 1: Convert 250 cc to milliliters. Multiply the cubic centimeter value by 1: 250 × 1 = 250. So 250 cc equals 250 mL, which is also 0.25 liters or about 8.45 US fluid ounces.

Example 2: A syringe is marked in cc and you need to record 7.5 cc in milliliters. Multiply by 1: 7.5 × 1 = 7.5. So 7.5 cc equals 7.5 mL, which is about 1.5 US teaspoons.

Frequently Asked Questions

Is a cubic centimeter the same as a milliliter? Yes. One cubic centimeter (cc or cm³) is exactly equal to one milliliter (mL). A milliliter is defined as the volume contained in a cube one centimeter on each side, so the two units describe the same amount of volume and convert one to one.

Why do syringes use cc and mL together? Medical syringes are often printed with both cc and mL because the units are equal and different fields prefer different labels. A dose written as 5 cc is the same as 5 mL, so you can read either scale without converting.

Can you convert plain centimeters to milliliters? Not directly. A plain centimeter measures length, while a milliliter measures volume, so they are not the same kind of quantity. This conversion only works when "centimeters" is shorthand for cubic centimeters, which is the volume unit that equals a milliliter.
