Conversion Formula

To convert quarts (qt) to gallons (gal), you use the formula:

Gallons = Quarts ÷ 4

This is because one gallon contains exactly 4 quarts. By dividing the number of quarts by 4, you find how many whole gallons fit into that volume. For example, if you have 12 quarts:

• Step 1: Recognize 1 gal = 4 qt
• Step 2: Divide 12 qt by 4
• Step 3: 12 ÷ 4 = 3 gal

That means 12 quarts equals 3 gallons.

Conversion Example

• Convert 20 quarts to gallons:
  • Step 1: 1 gal = 4 qt
  • Step 2: Divide 20 qt by 4
  • Step 3: 20 ÷ 4 = 5 gallons
  • Result: 20 qt equals 5 gal
• Convert 7 quarts to gallons:
  • Step 1: 1 gal = 4 qt
  • Step 2: 7 ÷ 4 = 1.75 gallons
  • Result: 7 qt equals 1.75 gal
• Convert 3 quarts to gallons:
  • Step 1: 1 gal = 4 qt
  • Step 2: 3 ÷ 4 = 0.75 gallons
  • Result: 3 qt equals 0.75 gal
• Convert 15 quarts to gallons:
  • Step 1: 1 gal = 4 qt

Conversion FAQs

Why is the conversion factor between quarts and gallons 4?

Because in the US system, one gallon is defined as exactly 4 quarts. This division comes from historical standards of volume measurement. So to get gallons from quarts, you divide the number of quarts by 4, reflecting that each gallon contains 4 equal parts called quarts.

Can I convert quarts to gallons for dry measurements?

While quarts and gallons measure volume, they are mostly used for liquids. Dry volume can be measured in quarts too but conversions for dry ingredients may vary because of density. For dry materials, weight is often preferred, but if volume is used, the same 4 quarts per gallon ratio applies.

Is the conversion the same in the UK?

No, the UK uses the imperial gallon which is larger than the US gallon. Therefore, converting quarts to gallons in the UK would use a different factor because the imperial gallon equals 4.54609 liters while the US gallon equals 3.78541 liters. The US quart to gallon ratio is fixed at 4, but the sizes differ internationally.

What if I want to convert gallons back to quarts?

To convert gallons to quarts, multiply the number of gallons by 4, since each gallon contains 4 quarts. For example, 3 gallons times 4 equals 12 quarts. This is the inverse of dividing quarts by 4.

Does temperature affect the conversion between quarts and gallons?

The conversion between quarts and gallons is a fixed ratio based on volume units, so temperature doesn’t affect the math. However, liquids expand or contract with temperature, so actual liquid volume might slightly vary, but the quart to gallon conversion number remains unchanged.
