### What Is Capacity?

Capacity refers to the amount of space inside a container or an object that can be filled with a fluid, grain, or other materials that can flow and take the shape of their container. It is a measure of volume, particularly in the context of how much liquid a container can hold. Understanding capacity is essential for numerous everyday activities, from cooking to fueling a car, and is critical in various scientific and industrial applications.

### Units of Capacity

The units used to measure capacity vary significantly depending on the system of measurement (metric or imperial) and the application. Here’s an overview of the primary units:

### Metric System

Liters (L) – The liter is the base unit of volume in the metric system, commonly used worldwide for everyday liquids such as beverages, gasoline, and water. One liter is the volume of a cube that measures 10 centimeters on each side.

Milliliters (mL) – A milliliter is one-thousandth of a liter, often used to measure smaller volumes. Common uses include measuring ingredients in cooking, medicine doses, and chemical solutions in laboratories.

Cubic Meters (m<sup>3</sup>) – Though not strictly a unit of capacity, cubic meters are also used to measure volume, especially for larger quantities like swimming pool volumes, freight containers, and room sizes.

### U.S. Customary Units

Gallons (gal) – Used widely in the United States, the gallon is a standard unit for measuring larger volumes of fluids like milk, gasoline, and paint. The US gallon is defined as 231 cubic inches or approximately 3.785 liters.

Quarts (qt) – A quart is one-fourth of a gallon, used to measure both liquids and dry substances. Common applications include cooking measurements and engine oil volumes.

Pints (pt) – A pint is half a quart. It is often used in the U.S. for measuring beverages and sometimes smaller amounts of produce.

Cups – A cup is a common volume measure in cooking, equal to half a pint. Recipes frequently use cups for both liquid and dry ingredients.

Fluid Ounces (fl oz) – This unit is used to measure smaller volumes of liquids, such as in cooking or serving sizes of beverages.
