Quick Answer
One cup equals 8 fluid ounces for liquid ingredients, which is also 16 tablespoons or about 237 milliliters. Dry ingredients are different because they measure by weight: a cup of all-purpose flour weighs about 4.5 ounces, and the weight changes with each ingredient. Always use a liquid measuring cup for liquids and a dry measuring cup for dry ingredients.

There are so many moments when we stop to think how do you convert cups to ounces? Sure you can quickly find and use an online calculator, but understanding the differences between dry and liquid conversions is crucial to the success of baking and liquid recipes.
There are many quick calculated methods on the web, which is great at times, but this guide will help you retain the information so you can use it every time you get stuck. We cover converting ounces to cups, tablespoons and teaspoons to cups, and explain fluid ounces versus dry ounces. This chart is so helpful so you have the tools you need for culinary success!
Why Ounces and Cups Get Confusing
Click to see the measuring science
- An ounce is two different things. A fluid ounce measures volume (how much space a liquid takes up) while a dry ounce measures weight. One ounce of weight is about 28.35 grams in the US customary system.
- Dry ingredients go by weight. A cup of flour weighs about 4.5 ounces while a cup of honey weighs about 12 - the same volume, very different weights. That is why bakers love kitchen scales.
- Liquids go by volume. Every liquid fills a cup the same way, so 1 cup of any liquid is always 8 fluid ounces. Measuring 4 ounces of lime juice for a Margarita is much different than measuring 4 ounces of flour for Chocolate Chip Cookies.
- There are even two kinds of weight ounces. The avoirdupois ounce is used for measuring most goods, and the troy ounce is used for precious metals like gold and silver.
- Flour settles in shipping. Flour is sifted before it is packaged but becomes compact in transit, so fluff and sift before measuring for the best results.

Equipment for Measuring
When determining how many cups in an ounce the proper kitchen tools are needed. There are three different tools needed for measuring dry and liquid ingredients:
- Granulated Measuring Cups - used for dry ingredients as they can be leveled off for an exact measurement. Either shake or level off with the flat part of a butter knife, and never pack down flour.
- Liquid Measuring Cups - used for fluid and liquid ingredients. They come in glass or plastic and indicate cups, ounces, and milliliters. I love to use my large Pyrex one as a mixing bowl or for measuring the amount of soup a recipe makes and then store it in the same container.
- Measuring Spoons - used for tablespoons and teaspoons. Make sure to level them off with a knife when using dry ingredients.
How to Measure Dry and Liquid Ingredients
Filling dry measuring cups
- Select the right cup size: choose the dry measuring cup size that matches the amount you need. Common sizes include 1 cup, ½ cup, ⅓ cup, and ¼ cup.
- Fluff and stir dry ingredients: before measuring dry ingredients like flour or sugar, fluff them up in their container with a spoon and gently stir to loosen the texture and eliminate settling.
- Spoon into the cup: use a spoon to scoop the dry ingredient into the measuring cup, overfilling slightly.
- Level off the top: sweep a flat-edged tool, such as the back of a knife, across the top of the measuring cup to create an even surface.
- Read at eye level: bending down or looking from an angle can distort the reading.
Filling liquid measuring cups
- Select the right cup size: common sizes include 1 cup, 2 cups, and 4 cups.
- Place on a flat surface: set the measuring cup on a level surface for an accurate measurement.
- Pour the liquid slowly: let it settle and eliminate air bubbles, filling just below the desired line.
- Check at eye level: read the measurement at the bottom of the curved meniscus (the slightly concave surface of the liquid).
Butter, Shots, and British Cups
Measuring butter and coconut oil: butter and coconut oil should be measured in liquid cups. Butter is typically found in ½ cup sticks or 8 tablespoons, and if made in the United States, the packaging is labeled with ¼ cup, ½ cup, and tablespoon marks. Pack butter or coconut oil in a liquid measuring cup with a spoon and level it off to measure properly.
How many ounces is a shot? There are 2 tablespoons in a 1 ounce shot. So if you are making a cocktail and do not have a shot glass around, measure two tablespoons of the alcohol.
British and American measuring cups: in the UK, measuring cups are typically labeled in milliliters and liters for liquids and grams and kilograms for dry ingredients, and British recipes often rely on weight for greater precision. American recipes frequently use volume. 1 UK cup is 250 mL while 1 US cup is 240 mL, so be aware of which system a recipe uses and adjust accordingly.
These conversions come in handy across the site, from an 8-cup batch of apple cider to a single 8-ounce glass of lemon salt water or doubling the sauce for cottage cheese mac and cheese.
Frequently Asked Questions (FAQs)
One cup of liquid ingredients is the same as 8 fluid ounces. Dry ingredients vary by weight, so they should be measured with a dry measuring cup or weighed in grams for accuracy.
