Cups to Quarts Converter
This calculator converts between US cups and US quarts, the two volume units most often seen in American recipes, and it works in either direction so you are never stuck doing the maths yourself. Choose whether you are converting cups to quarts or quarts to cups from the dropdown, then enter the amount you want to convert, and the result updates instantly as you type. Because a US quart always equals exactly 4 cups, the conversion is precise rather than a rounded approximation. Alongside the converted figure you also get the equivalent in millilitres and litres, since New Zealand kitchens measure in metric rather than cups and quarts, plus a quick reference panel showing how a cup relates to pints, fluid ounces and millilitres, and a table of common conversions running from 1 up to 20 cups. This is handy whenever you are following a US recipe, scaling a batch of soup, sauce or stock up or down, or working out how much liquid to buy before a big cook-up or preserving session. Keep in mind this tool uses US customary measurements, noticeably smaller than the old imperial quart once used here, so do not assume a US quart matches an imperial one. The metric figures shown are rounded for everyday use, so for precise baking, measure with a jug marked in millilitres rather than cup measures alone.

How to Convert Cups to Quarts
In the US customary system of measurement, 1 quart is equal to 4 cups. This makes the conversion straightforward: divide the number of cups by 4 to get quarts, or multiply the number of quarts by 4 to get cups.
Cups to quarts: quarts = cups ÷ 4
Quarts to cups: cups = quarts × 4
Worked Example
Say a recipe calls for 8 cups of stock and you want to know how many quarts to buy at the store. Divide 8 by 4, which gives 2 quarts. So 8 cups equals exactly 2 quarts, or about 1.89 litres.
Why Is a Quart Called a Quart?
The word "quart" comes from the Latin "quartus," meaning fourth, because a quart is one quarter of a US gallon. Since a gallon contains 16 cups, a quart (a quarter of a gallon) contains 4 cups. The same logic applies to pints: a pint is half a quart, so it contains 2 cups.
US Customary vs Imperial vs Metric
This converter uses US customary units, the standard used in most online recipes. It is worth noting that a US quart (about 946 ml) is smaller than an imperial quart (about 1,136 ml), which was historically used in New Zealand, the UK, and Australia before metrication. New Zealand kitchens now use the metric system, so recipes and packaging here are given in millilitres and litres rather than cups and quarts. If you are following a US recipe, this converter helps you work out how much volume you actually need, which you can then measure using millilitres.
Cups, Pints, Quarts and Gallons
| Unit | Equals | In Cups |
|---|---|---|
| 1 cup | 0.5 pint / 0.25 quart / 0.0625 gallon | 1 cup |
| 1 pint | 2 cups / 0.5 quart | 2 cups |
| 1 quart | 2 pints / 4 cups | 4 cups |
| 1 gallon | 4 quarts / 8 pints | 16 cups |
