Ounces to Cups Converter – Convert Oz to Cups

Use this online ounce-to-cups converter to easily calculate how much a given number of ounces of water, milk, flour, butter, sugar, salt, rice, and custard is equivalent to.

What is an Ounce?

An ounce is a unit of weight (mass) or volume used in various systems, including the Imperial system and the United States customary system.

There are two common types of ounces:

1. Avoirdupois Ounce (Weight/Mass): This is the most commonly used ounce in the United States for measuring weight. One avoirdupois ounce is equivalent to approximately 28.35 grams. There are 16 avoirdupois ounces in an avoirdupois pound.
2. Fluid Ounce (Volume): This is used to measure liquids. In the United States, one fluid ounce is equivalent to approximately 29.57 milliliters in the US customary system. However, in the Imperial system, which is used in some other countries, a fluid ounce is about 28.41 milliliters.

What is a Cup?

A cup is a unit of volume commonly used in cooking to measure both liquids and solids. The size of a cup varies by country and by context, but here are the two most common definitions:

1. US Customary Cup: In the United States, a standard cup (used for cooking and nutritional labeling) is equal to 8 US fluid ounces, which is about 237 milliliters. The US cup is commonly used in recipes in the United States and many other countries that rely on US-based cooking books or food resources.
2. Imperial Cup (UK): The UK (Imperial) cup is no longer in common use, but it was defined as 10 Imperial fluid ounces, which is approximately 284 milliliters. This was used in pre-1970s recipes in the UK, but the UK now typically uses metric measurements in recipes.

How to Convert Ounces and Cups?

Convert ounces of salt to cups

Task:

Convert ten ounces of salt to cups

Formula:

ounces/8.3454 × density = cups

Calculation:

Density of salt is 1.28 g/mL

10 / 8.3454 x 1.28 = .93615 cups

Result:

.93615 cups

Convert ounces of milk to cups

Task:

Convert 16 ounces of milk to cups

Formula:

ounces/8.3454 × density = cups

Calculation:

Density of milk is 1.03 g/mL

16 / 8.3454 x 1.03 = 1.8615 cups

Result:

1.8615 cups

How Many Ounces in a Cup?

In the United States, the standard measurement for a cup is 8 fluid ounces (fl oz). This is used for measuring liquids. For dry ingredients, the weight in ounces can vary depending on the ingredient's density. However, when a recipe calls for a cup of a dry ingredient, it is typically refers to a volume measurement, not weight.

For example:

• 1 cup of water or other similar density liquids weighs approximately 8 ounces.
• 1 cup of flour typically weighs around 4.25 to 5 ounces, depending on the type of flour and how it is measured (sifted, spooned, scooped, etc.).

Ounces of salt to Cups of salt

Converting ounces of salt to cups can be a bit tricky because salt can vary greatly in density depending on its type and granule size. However, as a general reference, we can use the approximation that 1 cup of table salt is roughly 10 ounces. Keep in mind that this is a rough estimate and for precise measurements, especially in cooking or baking, it's best to weigh your ingredients.

Ounces of rice to Cups of Rice

Converting ounces of rice to cups can vary slightly depending on the type of rice and how it's packed into the cup. However, a general approximation is that 1 cup of uncooked rice weighs about 6 to 7 ounces. For the purpose of this table, I'll use the average of 6.5 ounces per cup for the conversion. Please be aware that for precise measurements, especially when cooking, it's best to use a kitchen scale.

Here is a table converting ounces of rice to cups of rice from 1 to 10 ounces:

Ounces of Rice	Cups of Rice (approx.)
1	0.15
2	0.31
3	0.46
4	0.62
5	0.77
6	0.92
7	1.08
8	1.23
9	1.38
10	1.54
