# How many Ounces are in a Cup?

To figure out how many ounces are in a cup, you have to consult the Oracle atop Mt Olympus during a full moon at the beginning of Spring’s first blossom. Just kidding. Read on to find out how!

Actually, it isn’t that tough, so don’t worry about having to book any flights, unless of course you are ready for a vacation to Greece.

In fact, you can simply read on to understand how many ounces are in a cup. Who knows? Maybe you will become the next Oracle… Or at least the wisest one in your kitchen, capable of seeing the future of the next recipe at the very least.

The easy answer is 1 cup equals 8 fluid ounces.

## Fluid Ounces And Dry Ounces

There is a difference between fluid ounces and dry ounces. When you see “fl.” before “Oz.” in the measurement then that stands for “fluid ounces” (fl. oz.).

A fluid ounce actually doesn’t necessarily weigh the same as a weighed dry ounce. A fluid ounce of olive oil, for example, doesn’t have the same weight as a dry ounce of sugar for example.

In fact, in most cases, you cannot equate the measurements of a fluid ounce to a dry ounce. One exception is water, but that is only because approximately 16 ounces of water does equal about a pound.

But that of course depends if the water is heavy with minerals or distilled to just pure H2O. For all intents and purposes though, sixteen ounces of distilled water equals a pound.

But, you still need to understand the difference between fluid ounces, which measures volume, and dry ounces, which measures weight.

Here is a handy table showing fluid ounces in a cup.

## The Difference Between Volume and Weight

A fluid ounce actually measures the volume of liquid. Conversely, a dry ounce measures weight.

Unfortunately, the two measures rarely equal each other. The good news is a cup measure still comes in handy for measuring dry and wet ingredients equally when it comes to using a cup for recipes.

Liquid and dry measurements are different. But how different? Well we can start with the lingo. Ounces and Fluid Ounces.

Measuring volume defines how much is needed to fill a specific measurement. Measuring weight tells you how much mass there is. An ounce of cotton candy looks huge compared to an ounce of Pop Rocks, but they both have the same dry weight, when measured as an ounce.

But, a fluid ounce of maple syrup and a fluid ounce of lemon juice both fill up a wet measurement cup to the same fluid ounce line – even though they weigh differently in terms of actual density.

Here is another way to picture it…

A cup of chocolate chips weighs a little more than that same cup measured to the line with melted chocolate chips. So, a fluid ounce of melted chocolate chips is actually about 1 and 1/4 cups of dry chocolate chips because a fluid oz of chocolate is about 1.25 ounces of chocolate chips.

In recipes, any wet ingredients measured in imperial cups assumes those standards. That is why cup measures have those nifty lines on the side that measure the increments in ounces, cups, pints, and quarts depending on the size of your cup measure.

## Imperial Cup Measurement and Metric Cup Measurements

Before the metric system, there was a hodgepodge of weight standards around the world. Eventually, everything became sort of standardized, but there are still differences. The types of measurement specification standards include:

• Metric System
• English Imperial
• U.S. Customary Imperial
• Natural Units
• Non-Standard Units

Basically, metric system measurements are the most universal, and get broken down into fluid measurements, milliliter, liter, and kiloliters, and dry measurements of milligram, gram, and kilo to describe mass weight.

Natural and Non-Standard units are distance measurements like inch, foot, span, hand, mile and stuff like that. You won’t need those unless a recipe calls for three yards of uncut noodles or something. Don’t see it happening, but you never know.

Imperial measurements, both British and US, are what most people use in the kitchen and those include teaspoons (tsp), tablespoons (tbsp), cups, pints, quarts, and gallons, ounces, pounds, depending on wet or dry weights.

## Are British and US Imperial Ounces, Cups, and Pints the Same?

Life would be so much easier if “all things being equal” actually meant equal with imperial cup, ounce, pint, quarts, and gallon measurements.

Because, while a US imperial cup is slightly larger than a UK imperial cup, a British pint actually is 20 fluid ounces whereas the standard imperial American pint measures 16 ounces! Go figure.

That is what happens you start a revolutionary war with a tea party.

Luckily, whether you use British imperial cups and spoons to measure or you use US versions, then you don’t have to worry since ratios will be consistent as long as you use one or the other.

The tricky part is when you are reading measurements in an English cookbook but using US imperial measurement devices. In which case, sometimes a measurement conversion calculator might be useful.

## Tablespoons in a Cup

One of the most common questions is how many tablespoons in a cup. Measuring this first requires some discipline keeping things level.

As long as the measurements are all equally leveled, then 16 tablespoons make one cup. So eight tablespoons are half a cup, and 32 tablespoons equal two cups, or one pint.

## Handy Tips on Using a Cup to Measure Ounces

• Imperial cups for measuring dry ingredients have a straight edged top to make leveling the contents easier.
• A fluid cup measure usually has a spout for pouring and the measurement line is just under the top of the rim, so you don’t spill when you pour things out.
• If you need precise dry weight measurements of ingredients in ounces, then a digital kitchen scale is the way to go.
• When weighing on a scale, put your empty cup measure on the scale, then turn on the scale. The scale will show a zero balance and you can add your ingredients to the cup until it makes an ounce.
• For wet ounces, the fluid measurements work regardless of the wet ingredients like water, oil, syrup, etc.
• Use a butter knife or similar edged utensil to create level measurements by scraping off any excess heaping portions in your cup.

## Which is Better for Recipes, Imperial or Metric Measurements?

In almost all cases, chefs prefer to still use imperial measurements for recipes, regardless of the difference in UK and US imperial measurements. Why isn’t a cup of liquid the same?

The imperial system is simply more convenient in a lot of respects than the metric system. Don’t get me wrong. The metric system makes a lot more sense when super accuracy is required, but the imperial systems makes things easier.

You don’t have to weigh everything out using imperial measures because most recipes measure ingredients in imperial units.

And, in terms of fluid or solid, wet or dry, the imperial measuring utensils pretty much are interchangeable.
