To convert milliliters (mL) to cubic centimeters (cm³), you need to understand that these two units are equivalent. This means that 1 mL is exactly equal to 1 cm³. Therefore, no complex conversion is needed. If you have a volume in milliliters, it is already the same number in cubic centimeters. For example, if you have 5 mL, it is equal to 5 cm³. This equivalence is because both units measure volume and are based on the metric system, where 1 milliliter is defined as the volume of a cube that measures 1 centimeter on each side.
