Ounces1 and quarts2 are measurements which are used mostly in the USA because in most other countries the more understandable metric system has been adopted. Now almost all the Europe uses liters instead of these units.
Imperial and US Systems
There are two different kinds of quarts: imperial and US. If we are talking about US customary units, we know that one fluid quart consists of 2 pints, 4 cups, and 32 ounces. The US quart equals to about 0.95 liters. The imperial type of the quart has 2 imperial pints and 40 imperial ounces. It is equal to one imperial gallon which is approximately 1.14 liters.
But imperial quarts and ounces are used rather rarely, so you can just remember that there 32 ounces in one US liquid quart.
Now you know how many ounces in a quart, but if you need to find out how many teaspoons, tablespoons, cups or pints in one quart, you can consult the following table.
