Conversion Formula
The formula to convert quarts (qt) to gallons (gal) is to divide the number of quarts by 4. This is because 1 gallon contains exactly 4 quarts. When you have a quantity in quarts, dividing by 4 gives how many full gallons that quantity represents.
Mathematically, it looks like this:
gal = qt ÷ 4
For example, if you have 20 quarts, the calculation is:
20 qt ÷ 4 = 5 gal
The division works by grouping every 4 quarts into one gallon, so 20 quarts grouped into 5 sets of 4 equals 5 gallons.
Conversion Example
- Convert 12 quarts to gallons:
- Start with 12 quarts.
- Divide 12 by 4 (since 4 quarts = 1 gallon).
- 12 ÷ 4 = 3 gallons.
- So, 12 qt equals 3 gal.
- Convert 7 quarts to gallons:
- Start with 7 quarts.
- Divide 7 by 4.
- 7 ÷ 4 = 1.75 gallons.
- Therefore, 7 qt equals 1.75 gal.
- Convert 35 quarts to gallons:
- Start with 35 quarts.
- Divide 35 by 4.
- 35 ÷ 4 = 8.75 gallons.
- Hence, 35 qt equals 8.75 gal.
- Convert 2.5 quarts to gallons:
- Take 2.5 quarts.
- Divide 2.5 by 4.
- 2.5 ÷ 4 = 0.625 gallons.
- So, 2.5 qt equals 0.625 gal.

Conversion FAQs
Does the quart to gallon conversion change depending on liquid type?
No, the quart to gallon conversion remains the same regardless of the liquid type because it is a volume measurement. Whether you measure water, milk, or gasoline, 4 quarts always equal 1 gallon. The difference lies in weight or density, not volume units.
