Conversion Formula
The basic formula to convert quarts (qt) to gallons (gal) is:
Gallons = Quarts ÷ 4
Because one gallon equals exactly four quarts, dividing the quantity in quarts by 4 converts it to gallons. This works since gallons and quarts both measure volume, but gallons are a larger unit.
Example calculation for 12 quarts:
- Start with 12 quarts.

- 12 ÷ 4 = 3 gallons.
- So, 12 quarts equals 3 gallons.
Conversion Example
- Convert 16 quarts to gallons:
- Take 16 quarts.
- Divide 16 by 4.
- 16 ÷ 4 = 4 gallons.
- Therefore, 16 quarts equals 4 gallons.
- Convert 5 quarts to gallons:
- Start with 5 quarts.
- 5 ÷ 4 = 1.25 gallons.
- So, 5 quarts equals 1.25 gallons.
- Convert 8 quarts to gallons:
- 8 quarts divided by 4 equals 2 gallons.
- Because 8 ÷ 4 = 2, the result is 2 gallons.
- Convert 3 quarts to gallons:
- 3 ÷ 4 = 0.75 gallons.
- So, 3 quarts equals three-quarters of a gallon.

Conversion Definitions
Quart (qt): A quart is a unit of volume measurement in the US customary system equal to one-fourth of a gallon or two pints. It’s used frequently in cooking, liquid containers, and fuel measurements. One quart equals 32 fluid ounces or approximately 0.946 liters.
Gallon: A gallon is a larger volume unit in the US customary system, consisting of four quarts. It is often used to measure liquids like milk, gasoline, and water. One gallon equals 128 fluid ounces or approximately 3.785 liters, making it substantially bigger than a quart.
Conversion FAQs
Why do we divide quarts by 4 to get gallons?
Since one gallon contains exactly four quarts, dividing quarts by 4 converts the smaller unit to the bigger one. This simple fraction reflects how many times the quart fits into a gallon. For example, 8 quarts divided by 4 equals 2 gallons because 8 is two times 4.
Can I convert quarts to gallons for any volume?
Yes, the conversion works for any quantity, even fractional or negative values. Whether you have a small amount like 0.5 quarts or a large amount like 100 quarts, dividing by 4 converts it accurately to gallons. Negative values represent volumes below zero, which might be used in some calculations.
Is the conversion factor the same in UK measurements?
No, the UK uses the imperial gallon, which is different in size from the US gallon. The imperial gallon equals about 4.546 liters, larger than the US gallon’s 3.785 liters. Therefore, converting quarts to gallons in the UK would require a different conversion factor.
How precise is the conversion when using decimals?
The conversion is exact mathematically, but when decimals are involved, rounding can introduce small errors. Using more decimal places improves accuracy. For instance, 5 quarts equals 1.25 gallons exactly, but 7 quarts is 1.75 gallons, which can be represented precisely or rounded depending on need.
Why is the quart used if gallons exist?
Quarts provide a smaller, more convenient measurement unit for certain volumes. When measuring liquids in smaller quantities, quarts avoid using fractions of a gallon. This makes recipes, fuel quantities, and other measurements easier to handle without decimals or fractions.
