About US liquid quart (qt)
The US liquid quart (qt) is a unit of volume equal to 2 US liquid pints or 32 US fluid ounces, approximately 946.4 milliliters. It is used for beverages, dairy products, soups, and motor oil in the United States. Motor oil is typically sold in 1-quart bottles. Soups, broths, and juices are commonly packaged in 32-oz (1-quart) cartons. The US liquid quart is smaller than the imperial quart (1,136.5 mL).
A standard carton of chicken broth is 32 fl oz (1 qt, ~946 mL). Motor oil is sold in 1-quart bottles.
About Imperial cup (imp cup)
The imperial cup is a unit of volume equal to half an imperial pint, approximately 284.1 milliliters. It was historically used in British cooking recipes and is still found in older UK and Commonwealth cookbooks. The imperial cup is distinct from the US legal cup (240 mL) and the Australian metric cup (250 mL). Since the UK's adoption of metric measures, the imperial cup has largely fallen out of use, replaced by milliliters and the 250 mL metric cup.
Older British recipes (pre-1970s) may call for cups measured as imperial cups (~284 mL). A standard UK teacup holds about 1 imperial cup.
US liquid quart – Frequently Asked Questions
How many cups are in a quart?
There are 4 US cups in one US liquid quart: 1 quart = 32 fl oz and 1 cup = 8 fl oz. The full chain: 2 cups = 1 pint, 2 pints = 1 quart, 4 quarts = 1 gallon.
How many milliliters are in a quart?
One US liquid quart equals approximately 946.4 mL (just under one liter). One imperial quart equals approximately 1,136.5 mL.
Why is motor oil sold in quarts in the US?
Most car engines require 4–6 quarts of oil per oil change, making the quart a practical single-container size. In metric countries, motor oil is sold in 1-liter or 4-liter containers.
How does a US quart compare to a liter?
One US quart (946 mL) is about 5.7% smaller than one liter (1,000 mL). Substituting 1 L for 1 qt adds about 54 mL — usually negligible in large-batch cooking.
What is the difference between a liquid quart and a dry quart?
A US liquid quart is 946.4 mL; a US dry quart is 1,101.2 mL — about 16% larger. Dry quarts are used for grain, produce, and dry goods. The distinction matters in agricultural and commercial contexts.
Imperial cup – Frequently Asked Questions
How many milliliters is an imperial cup?
One imperial cup equals approximately 284.1 mL — half an imperial pint (568 mL). This is larger than both the US legal cup (240 mL) and the Australian metric cup (250 mL).
Is the imperial cup still used in the UK?
The imperial cup is largely obsolete in modern UK cooking, which now uses metric measurements. It may appear in old British recipe books published before the 1970s metric changeover.
How does the imperial cup compare to the US cup?
An imperial cup (284.1 mL) is about 18% larger than a US legal cup (240 mL). When using old British recipes in the US, 1 imperial cup ≈ 1.18 US cups — worth adjusting in baking.
What replaced the imperial cup in British recipes?
Modern British recipes use metric measures: milliliters (mL) for liquids and grams (g) for solids. The BBC and major UK food publishers phased out cup measures in favor of grams through the 1970s–1990s.
How many imperial cups are in an imperial gallon?
There are 16 imperial cups in one imperial gallon (8 pints × 2 cups/pint = 16 cups).
