Conversion Formula
The formula to convert quarts to gallons is:
Gallons = Quarts ÷ 4
This works because 1 gallon contains exactly 4 quarts. So, dividing the total quarts by 4 gives you the equivalent in gallons. For example, if you have 20 quarts:
- Start with 20 quarts.
- Divide 20 by 4.
- 20 ÷ 4 = 5 gallons.
This method can be used for any amount of quarts to find the gallons value.
Conversion Example
- Example: Convert 12 quarts to gallons
- Begin with 12 quarts.
- Divide 12 by 4 (since 4 quarts = 1 gallon).
- 12 ÷ 4 = 3 gallons.
- So, 12 quarts equals 3 gallons.
- Example: Convert 7 quarts to gallons
- Start with 7 quarts.
- Divide 7 by 4.
- 7 ÷ 4 = 1.75 gallons.
- This means 7 quarts is 1.75 gallons.
- Example: Convert 33 quarts to gallons
- Take 33 quarts.
- Divide 33 by 4.
- 33 ÷ 4 = 8.25 gallons.
- Therefore, 33 quarts equals 8.25 gallons.
- Example: Convert 4 quarts to gallons
- Use 4 quarts.
- Divide 4 by 4.

Conversion Definitions
Qts (Quarts): A quart is a unit of volume in the US customary and imperial systems, mostly used for measuring liquids. One quart is equal to one fourth of a gallon, or 32 fluid ounces. Quarts are commonly used for cooking, fuel, and liquid measurements.
Gallons: A gallon is a unit of volume measurement in the US customary system, larger than quarts. One gallon equals 4 quarts or 128 fluid ounces. Gallons are used to measure larger liquid quantities like gasoline, milk, or water in everyday and industrial uses.
Conversion FAQs
Can the conversion from quarts to gallons be used for dry ingredients?
While quarts and gallons primarily measure liquid volume, they sometimes apply to dry volume in cooking. However, dry quarts and liquid quarts differ slightly in size, so converting dry quarts to gallons might not be exact using the liquid conversion formula without adjustment.
Why is 1 gallon equal to 4 quarts and not some other number?
This relationship comes from traditional British measurements adapted in the US. The gallon was divided into four equal parts called quarts for easier use and calculation. This standardization makes conversions straightforward and consistent in measurements.
Does temperature affect quart to gallon conversion?
Volume measurements like quarts and gallons assume standard temperature conditions. Extreme temperatures might cause liquid expansion or contraction, but the numerical conversion ratio between quarts and gallons stays constant regardless of temperature.
Is the conversion factor different in other countries?
The US gallon and quart differ from the imperial gallon and quart used in countries like the UK. Therefore, converting quarts to gallons in imperial units uses a different ratio. The US conversion formula (1 gallon = 4 quarts) applies only to US customary units.
Can I convert quarts to gallons using simple multiplication?
No, because 1 gallon equals 4 quarts, so you divide quarts by 4 to get gallons. Multiplying quarts by 4 would give a much larger, incorrect number. Remember to always divide to convert quarts into gallons properly.
