What standard unit is commonly used to measure the volume of liquids like milk or water?

The liter (L) is the standard unit most commonly used to measure the volume of liquids like milk or water.

Explanation:

Standard Unit in the Metric System

A liter (symbol: L) is the internationally accepted metric unit for liquid volume.

It is widely used in everyday life for measuring beverages, cooking ingredients, and packaged liquids such as milk, juice, or bottled water.

Relation to Other Units

1 liter = 1,000 milliliters (mL).

In scientific contexts, liquid volume may also be expressed in cubic meters (m³), where 1 m³ = 1,000 liters.

In countries using the imperial system (like the U.S.), liquid volume is often measured in gallons, quarts, pints, or cups, but liters are still recognized for scientific and global trade purposes.

Why Liters are Commonly Used

The liter is part of the International System of Units (SI), making it universally accepted.

It provides consistency in trade, science, and daily life, ensuring people worldwide can understand and compare quantities accurately.
