Liters to Gallons Conversion

Professor Greenline Explaining Math Concepts

We can measure the volume of liquids using units like milliliters, liters, ounces, quarts, or gallons. Different units are used to measure different quantities. A liter is a metric unit of volume commonly used for measuring liquids like beverages and water. A gallon is a larger unit of volume commonly used in the United States to measure larger quantities of liquid. Sometimes we need to change liters to gallons to make it easier to understand volumes. In this topic, we will learn how to convert liters to gallons.
