What is Volume Conversion?

Volume conversion means changing a liquid measurement from one unit to another. In this lesson, we're learning how to convert between quarts and gallons, which are units used in the US customary system for measuring liquids.
Why do we need to convert? Different recipes and instructions use different units. Knowing how to convert between quarts and gallons helps us follow directions accurately whether we're cooking, doing science experiments, or measuring liquids for any purpose.
One gallon equals 4 quarts. To convert quarts to gallons, we divide the number of quarts by 4. Understanding this relationship helps us compare measurements and solve real-world problems.
Key Concept
1 gallon = 4 quarts. This relationship is the foundation for all quart-to-gallon conversions.
How to Convert Quarts to Gallons
