Definition
Noun: A milliliter is a metric unit of volume equal to one thousandth (1/1000) of a liter. It is a standard measurement for small amounts of liquid.
Usage
The word "milliliter" is used to quantify volume, particularly for liquids in scientific, medical, culinary, and everyday contexts. It is often abbreviated as ml or mL.

- The doctor prescribed a cough syrup dosage of 10 milliliters.
- This small bottle has a capacity of 30 ml.
Advanced Usage
- Cubic centimeter equivalence: In scientific contexts, especially in medicine and chemistry, 1 milliliter is defined as exactly equal to 1 cubic centimeter (cm³ or cc). This is because the liter is defined based on the cubic decimeter.
- Example: The syringe is filled with 3 ml, which is equivalent to 3 cc.
