Quart to Cups Converter calculator

Converts US quarts to cups or cups to quarts, using the exact 1 quart = 4 cups ratio.

Published 21 August 2026

What this calculator does

A US liquid quart is exactly 4 US cups, a fixed ratio rather than an approximation, so 1 quart to cups always works out to 4 cups regardless of what is being measured. The name itself is the clue: quart comes from quarter, as in a quarter of a gallon, and a gallon is 16 cups, so a quart is a quarter of that: 4 cups.

This calculator converts quart to cups or cups to quarts in either direction, and also shows the equivalent in millilitres and litres so a US recipe can be checked against metric kitchen measures without a separate lookup.

The formula

FormulaCups = quarts × 4; Quarts = cups ÷ 4 (US liquid measure)

Multiply quarts by 4 to get cups, or divide cups by 4 to get quarts. Both directions use the same fixed US measure: 1 US gallon = 4 quarts = 16 cups = 128 fluid ounces, so a quart sits exactly a quarter of the way through that ladder.

TermMeaning
QuartA US liquid measure equal to a quarter of a gallon, or 4 cups, or 32 US fluid ounces.
CupA US measure equal to 8 US fluid ounces, or 236.588 mL.
US liquid measureThese figures use the US customary cup and quart. A UK/Imperial quart is a different, larger volume (about 1.136 litres) and is not what this calculator converts.

When to use it

Scaling a recipe written in quarts

US recipes for stocks, soups and preserves are often written in quarts. Converting to cups makes the amount easier to measure out with standard kitchen cup measures, especially for a partial quart such as three-quarters of a quart.

Checking a recipe against metric measuring jugs

A cook working with a millilitre or litre measuring jug can convert a quart figure straight to millilitres here, rather than converting to cups first and then to millilitres separately.

Working out how many quart containers are needed

Converting a total number of cups needed, for example for a batch of soup or a canning project, into quarts shows how many quart-sized jars or containers to have on hand.

Worked examples

1 quart is 4 cups exactly, so every value in this table is that same quart amount multiplied by 4, with 2 quarts giving 8 cups and 4 quarts (1 gallon) giving 16 cups.

How many quarts is a given number of cups?

4 cups make up 1 quart, so 8 cups is 2 quarts, 12 cups is 3 quarts, and 16 cups is 4 quarts, which is also exactly 1 US gallon.

Questions

What is 1 quart to cups?

1 quart is exactly 4 US cups. This is a fixed definitional ratio, not a rounded approximation, so the answer is the same 4 cups every time for a US liquid quart.

Is a UK quart the same as a US quart?

No. This calculator uses the US liquid quart (4 US cups, about 946 mL). A UK/Imperial quart is larger, about 1.136 litres, because the Imperial and US gallon are different sizes. Check which system a recipe or container is using before converting.

What is quart in cups for a half quart?

Half a quart is 2 cups, following the same 4-cups-per-quart ratio. A quarter of a quart is 1 cup.

How many quarts are in a gallon?

There are 4 quarts in a US gallon, and since 1 quart is 4 cups, a gallon is 16 cups in total.
