What is the primary use of liters in measurements?

Liters are a unit of measurement primarily used to quantify volume. In practical applications, this means that liters are used to measure the capacity of liquids, such as water, gasoline, or any other fluid. When dealing with containers of various shapes and sizes, the volume indicates how much liquid the container can hold, which is essential in many fields such as cooking, chemical engineering, and environmental sciences.

In contrast to other forms of measurement:

• Length refers to the distance between two points, typically measured in units like meters or centimeters.

• Area pertains to the extent of a surface and is generally measured in square units, such as square meters or square feet.

• Weight measures the force exerted by gravity on an object, commonly expressed in grams or kilograms.

Thus, liters exclusively pertain to volume measurements, making it the appropriate choice for this question.
