1 gallon = 4 quarts (exactly). This applies to US liquid gallons. UK imperial gallon also has 4 quarts, but different sizes.

💡Think of it as: 4 quarters make a whole (gallon).

1 gallon = 4 quarts = 8 pints = 16 cups = 128 fl oz. Each step doubles: 1 quart = 2 pints = 4 cups = 32 fl oz.

💡Pattern: gallon ÷ 4 = quart ÷ 2 = pint ÷ 2 = cup.

Gallons to quarts: multiply by 4. Quarts to gallons: divide by 4. Example: 2.5 gallons = 2.5 × 4 = 10 quarts.

💡Half gallon = 2 quarts. Quarter gallon = 1 quart.

1 US quart = 946 ml = 0.946 liters. 1 US gallon = 3.785 liters. Round to 1 quart ≈ 1 liter for quick estimates.

💡A quart is very close to a liter — only 54ml difference!

Quart comes from Latin 'quartus' meaning fourth. A quart is one-fourth (quarter) of a gallon.

4 cups = 1 quart. So a gallon has 16 cups total (4 quarts × 4 cups).

No, a US quart (946ml) is slightly smaller than a liter (1000ml). They're close enough for rough estimates.
