Volume Units Conversion

US Customary Units of Volume

The US customary system uses units such as gallons, quarts, pints, cups, and fluid ounces. These are commonly used in cooking, grocery packaging, and everyday measurements in the United States.

Metric Units of Volume

The metric system is decimal-based and used worldwide for science, technology, and most everyday measurements. The primary liquid units are the liter (L) and milliliter (mL).

Relationship: 1 L = 1000 mL. Conversions involve shifting the decimal (base 10), which makes metric easy to work with.
