So how many ounces make a quart? The measuring system:

We’d love nothing more than to have a universal measuring system for all things recipe-related. However, that’s certainly not the case. That’s where the US Imperial System of Measurement really shines. 

As the name suggests, in the US, this system is used for, you guessed it, measurements. The Imperial System was first defined in the British Weights and Measures Act of 1824 and was named the “British Imperial System.” 

In 1832, after all the states were standardized, the US adopted the “British Imperial System, ” renamed the U.S. system (or U.S. Customary system). The only difference between the British imperial measurement and the U.S. systems of measurement is that in the United States, the number of ounces in quarts is larger than in the imperial quart of the British Imperial system. 

The US is one of the few countries globally that continues to use the Imperial System, where liquids are all types of things measured in feet, inches, pounds, ounces, and more. The rest of the countries quickly adopted the Metric System. (The United Kingdom uses the metric system as well. However, it still does use imperial fluid ounces for certain things such as returnable milk and beer containers.)

What’s the difference between dry ounces and liquid ounces? 

To put it simply, an ounce of liquid is basically the amount of water weighing one ounce. So a fluid ounce ( fl. oz.) is solely used to measure all types of liquids, and an ounce (oz) is for dry measurements only. A fluid ounce of water weighs a bit more than 1 oz. For example, 1 fl-oz = 1.04 oz wt. Remember, slight differences can make an impact in your cooking. 

Of course, the quart weight depends on the kind of liquid it is. Some liquids have lighter or heavier in mass. That’s why it’s important to also take into consideration the weight of liquids and dry ounces. Most often, oz is dry oz is used to measure ingredients flour, salt, pepper, sugar, chocolate, and more.
