## What is an Ounce?

An ounce is a unit of measure used to weigh out volume, weight, and mass. This accurate unit of measure is used in the United States of America, Myanmar, and Liberia to weigh out ingredients.

## What is a Cup?

Perhaps your favorite coffee cup pops into your mind when you think of a cup. However, when it comes to cooking and baking, proper measuring cups are available.

Measuring with cups is an easy and practical way of measuring ingredients. Most recipes online get measured in cups.

In the US, 1 cup equals ½ of a US pint.

In the metric system, 1 metric cup is 250 ml.

Tablespoons and teaspoons are the baby cousins of cups. When you purchase a set of measuring cups, you will likely buy a set of spoons too!

When calculating how many ounces in 1 cup, you first need to have a clear idea of cup measurements.

## Equipment for Measuring Cups

With regards to measuring dry ingredients and liquids, here are three critical sets of equipment. There are glass, plastic, and metal versions available in the different cups and spoons.

### Liquid Measurement Cups

Liquid measurement cups are designed to measure fluid ounces. These are brilliant for measuring out liquid ingredients. They are also used for portioning soups, sauces, etc. Read on for tips on how to measure wet ingredients accurately.

### Dry Measuring Cups

These cups are perfect to measure dry ingredients like sugar, flour, corn flour, etc. See below for tips on how to measure dry ingredients accurately.

### Measuring Spoons

Tablespoons and measuring spoons are great for measuring small ingredients in an instant. Use for both wet and dry ingredients.

## How to Fill Dry Measuring Cups

Here is how to measure dry ingredients accurately in a cup:

1. Ensure the dry ingredient is loose and lump-free. Sieving or lightly whisking the ingredient is an easy way to get rid of lumps. This is perfect for flour or sugar (powdered sugar). Humid environments can cause lumps and clumps to form.
2. Next, spoon the dry ingredient into the measuring cup. Fill it until it overflows.
3. Place the cup onto a stable and level surface.
4. Level the flour or dry ingredient off with the back of a knife or a straight utensil.

Do not pack the dry ingredient firmly into the cup. This can result in an inaccurate result.

## How to Fill Liquid Measuring Cups

Here is another crucial element when learning about how many ounces are in a cup. To correctly measure liquids, follow these directions:

1. Place the measuring cup on a flat surface. This will stabilize the receptacle.
2. Bend down to see the top level of the measuring cup.
3. Pour the liquid in until it reaches the surface (or just below the surface) line.

Note: Butter is considered a wet ingredient. To measure butter correctly in a cup, it must be soft.

### Fluid Ounces to Cups

There are 8 fluid ounces in 1 cup. This is according to the US system.

If using liquid ingredients, we measure them in fluid ounces.

### Dry Ounces to Cups

There are 4.5 dry-weight ounces in 1 cup. This is according to the US system.

With dry ingredients, you need to measure it by weight. There is a big difference between fluid and dry ounces. It is essential to keep this in mind.

## British Versus American Measuring Cups

The difference between US and UK measuring cups is tiny. There is absolutely no need to worry about converting between cups unless you have a very precise recipe.

A UK cup (in cooking) is 250 ml. The US measuring cup is 240 ml.

Other measurements to note:

• ½ UK cup is 125 ml
