How Many Cups in a Quart, Pint, and Gallon?
There are 4 cups in a quart, 2 cups in a pint, and 16 cups in a gallon. These three conversions come up constantly in cooking — scaling soup recipes, buying milk or stock, or converting a recipe written in pints to the cups you're used to measuring with.
Quick Reference Table
| Unit | Cups | Pints | Quarts |
|---|---|---|---|
| 1 cup | 1 | ½ | ¼ |
| 1 pint | 2 | 1 | ½ |
| 1 quart | 4 | 2 | 1 |
| 1 gallon | 16 | 8 | 4 |
How They All Connect
The easiest way to remember the relationship is that each unit doubles the one before it, except going from quart to gallon, which is a 4x jump:
1 pint = 2 cups
1 quart = 2 pints = 4 cups
1 gallon = 4 quarts = 8 pints = 16 cups
Think of it as nesting containers: a gallon holds 4 quarts, each quart holds 2 pints, and each pint holds 2 cups. If you picture them stacked inside each other, the math becomes easy to recall without memorizing four separate numbers.

When This Conversion Comes Up
This conversion is most useful in three situations. When scaling a soup, stock, or batch recipe written in quarts or gallons but you only have cup measures. When grocery shopping — milk, juice, and stock are often sold by the quart, pint, or half-gallon, and you need to know how that translates to the cups a recipe calls for. And when canning or large-batch cooking, where ingredients are commonly measured in quarts.
For converting between cups and smaller units like tablespoons and teaspoons, see the Cups to Tablespoons Calculator. For weight-based conversions (grams, ounces, pounds), use the Liquid Converter.
Metric Equivalents (Cups, Pints, Quarts, Gallons to Liters)
If a recipe or product label uses metric units instead, here's how US volume measurements translate to milliliters and liters:
| US Unit | mL | Liters |
|---|---|---|
| 1 cup | 236.6 ml | 0.24 L |
| 1 pint (2 cups) | 473 ml | 0.47 L |
| 1 quart (4 cups) | 946 ml | 0.95 L |
| 1 gallon (16 cups) | 3,785 ml | 3.79 L |
Because a US quart is almost exactly 0.95 liters, many cooks round it to "about 1 liter" for casual cooking — the 5.4% difference rarely matters outside of precise baking or canning. For a full walkthrough of converting an entire recipe (not just liquid volumes) to metric, see our guide on how to convert a recipe to metric.
US Measurements vs UK (Imperial) Measurements
If you're following a recipe from a UK, Australian, or Canadian source, watch out — the imperial pint and quart are larger than the US versions, even though they share the same name.
| Unit | US (fl oz) | Imperial/UK (fl oz) |
|---|---|---|
| 1 pint | 16 fl oz (473 ml) | 20 fl oz (568 ml) |
| 1 quart | 32 fl oz (946 ml) | 40 fl oz (1,137 ml) |
| 1 gallon | 128 fl oz (3.79 L) | 160 fl oz (4.55 L) |
The imperial pint is about 20% larger than the US pint. This matters most for drink recipes and any dish where a British, Irish, Australian, or Canadian source specifies "pints" or "quarts" — always check whether the source is using US or imperial measurements before converting to cups, since using the wrong ratio can throw off a whole batch recipe.
Worked Example: Scaling a Stock Recipe
Say a recipe calls for 3 quarts of chicken stock, but your measuring cup is the only tool on hand. Using the conversion above: 3 quarts × 4 cups per quart = 12 cups of stock needed. If you're instead working from a gallon-sized stockpot and want to know how many quart containers to fill for storage, divide the other way: 1 gallon ÷ 4 quarts per gallon = 4 quart containers per batch.
Frequently Asked Questions
How many cups are in a quart of milk?
A quart of milk contains 4 cups. This applies to any liquid — water, milk, broth, or juice — since quarts and cups are both volume measurements regardless of what's being measured.
How many cups are in a gallon of water?
A gallon contains 16 cups. This is useful for tracking daily water intake goals, which are often expressed in ounces or cups but sold by the gallon at the store.
Is a dry quart the same as a liquid quart?
No, slightly different. A US dry quart (used for produce like berries) is about 16% larger than a liquid quart. For cooking and baking, recipes almost always mean the liquid quart, which is what this guide and the standard 4-cups-per-quart conversion refer to.
How many quarts are in a gallon?
There are 4 quarts in 1 gallon. This is the most commonly needed conversion when buying liquids in bulk — a gallon of milk, for example, is the same as 4 quart containers.
How many pints are in a quart, and how many quarts in a half-gallon?
There are 2 pints in 1 quart, and a half-gallon equals 2 quarts (or 8 cups). Half-gallon containers are common for milk, orange juice, and ice cream in US grocery stores.
Do I need to adjust these conversions for thick liquids like broth or oil?
No — cups, pints, quarts, and gallons are volume measurements, so the conversion ratio stays exactly the same regardless of how thick or thin the liquid is. A cup of heavy cream and a cup of water both equal the same fraction of a quart.
