The difficulty in making recipes nowadays is a result of different measurement systems. Recipes that use both metric and US measurements are rare, making it more difficult for home cooks and baking enthusiasts to measure the right amounts of ingredients. This article is an in-depth guide that will give you a quick, easy, and comprehensive cup volume conversion. Jump to:
What is an ounce?An ounce is a measurement unit of weight (dry ounce) and volume (fluid ounce). An avoirdupois ounce (aka US dry oz) is used to measure dry ingredients (flour, nuts, seeds, sugar, etc.), equaling 1/16 pound or 28.35 grams. A troy ounce (aka British Imperial ounce) is mostly used to measure the mass of precious metals (gold, silver, platinum, etc.). It is equal to 31.10 g. But the dry ounces shouldn't be confused with fluid ounces (fl oz) that measure liquid ingredients such as milk, water, oil, etc. 1 US fluid ounce = 29.57 milliliters. 1 imperial fluid ounce = 28.4 milliliters. Measuring cupsWhich measuring cup do you need? There are many different types of cups worldwide, and it can be confusing to know which one is right for your needs. For example, there are US customary and legal cups, Imperial cups, Canadian, New Zealand, and Japanese cups. Different countries have their own standards for food weight or liquid capacity. So make sure to read a recipe through before you start. British vs American measuring cupsBritish and American measuring cups, also ounce measurements, differ because of the different measurement systems. In the United States, people use imperial measurements for recipes. In the United Kingdom and many other countries, it is common to use the metric system instead. 1 metric cup = 250 ml of water. 1 US cup = 237 ml of water. Liquid vs. dry measuring cupsWhat is the difference between dry cups and liquid ones? If you measure oil, milk, or juice, for instance, then you should use a wet measuring cup with a pour spout on the side. Please, don't confuse this type of cup with a coffee mug or a teacup. Liquid things are measured in fluid or liquid ounces. Dry ingredients such as flour, sugar, or potato starch should be measured with granulated measuring cups in dry ounces. Different dry ingredients have various rules for measuring them correctly. For example, flour should be scooped and leveled with the flat edge of a butter knife to remove excess flour from the top of the cup. Brown sugar should be packed into the cup. So dry measurements are used for weight, while liquid ones identify the volume of liquid. Please, read more about how to measure liquid and dry ingredients. Again and again, a kitchen scale is the one that provides the most accurate and precise measurement (aka right measurement) of ingredients. How many fluid ounces in a cupLet's dive into how many fluid ounces make a cup. 1 cup to ounces (1 c to fl oz)One US cup of liquid equals 8 fluid ounces, or 1 c = 8 fl oz One Imperial cup equals 10 fluid ounces, or 1 c = 10 fl oz 1 ounce to cups (1 fl. oz. to c)How much is one ounce? 1 US fluid ounce equals 0.125 US cup. 1 Imperial fluid ounce equals 0.1 Imperial cups. How to convert cups to ouncesTo convert US cups to US fluid ounces, multiply the number of cups by 8, where 8 is a conversion factor: US fluid ounces = cups x 8. To convert Imperial cups to Imperial fluid ounces, multiply the number of cups by 10, where 10 is a conversion factor: Imperial fluid ounces = cups x 10. Let's have a look at an example. How many ounces in 2 cups? 2 c x 8 = 16 fl. oz. (US system), so there are 16 US fluid ounces in 2 US cups. 2 c x 10 = 20 fl. oz. (Imperial system), so there are 20 Imperial fluid ounces in 2 Imperial cups. Cups to fl oz conversion chartThe chart below provides an easy-to-use guide for navigating the conversion rates.
