Conversion FAQs
Why do we divide quarts by 4 to get gallons?
Because one gallon contains exactly 4 quarts, dividing the number of quarts by 4 gives how many gallons are represented. This is a fixed ratio in the US customary measurement system, so the division makes direct sense without approximation.
Can I convert quarts to gallons in the metric system?
No, quarts and gallons belong to the US customary and imperial systems. The metric system uses liters and milliliters. To convert quarts to liters first, then convert liters to gallons if needed, but there’s no direct quarts-to-gallons metric conversion.
Are quarts and gallons used the same worldwide?

Is the conversion exact for all liquids?
The conversion between quarts and gallons is based on volume units, so it is exact for any liquid volume. However, density or weight of the liquid doesn’t affect this conversion since it’s purely volumetric.
Can I use this conversion for dry measurements?
Quarts and gallons are volume measurements and can be used for dry goods, but the accuracy depends on the material’s packing and density. For dry ingredients, weight measurements are often more accurate.
