Solution:įor most scenarious you'd be happy to round that up to three cups of flour while skimming just a bit off the top of the last one.įor your convenience, we present charts for some of the most used cooking ingredients, namely water, milk, and vegetable oil. Sample task: convert sixteen ounces of flour to cups, knowing that the density of flour is 0.67 grams per milliliter meaning that a cup holds 5.7 oz of flour. Solution:įor practical purposes, eight ounces of water equal one cup of water. Sample task: convert eight ounces of water to cups, knowing that the density of water is 1 gram per milliliter meaning that a US cup holds 8.5 oz of water. To do so, follow these instructions: Eight ounces of water to cups For example, a recipe might specify 8 ounces water and 16 ounces of flour, and you may want to convert those measurements to cups. The conversion from ounces to cups can be approached once the density of the substance to be converted is known. This can involve both research and math, and you can spare yourself the effort if you simply employ our oz to cups converter as long as the ingredient is among the list of supported ones. To answer the question, first learn what the density of the substance is, then divide its volume by the density to get the number of ounces in a cup. So if we take 7.7 ounces of oil it will fill a cup while 8.5 ounces of water will leave some empty space on the top. For example, a cup of water weighs about eight and a half ounces, while a cup of vegetable oil weighs just 7.7 ounces. Simply put, the weight in ounces of a given volume of an ingredient depends directly on the density of said ingredient. It depends on what is to be put in the cup. This holds especially true for sweets and desserts. Therefore, using volumes introduces unnecessary uncertainty in the preparation of a recipe and should be avoided when a kitchen scale is available. Ideally, one would not convert weight to volume (oz to cups) since this conversion requires the introduction of density in the calculation, and that can only be roughly estimated from averages. Both units are supported by our converter. An older unit still encountered is the Imperial cup which equals 284 ml. The most widely used is the US legal cup, defined as containing 240 ml of volume. The cup is a unit of volume with two definitions that one can encounter in recipes. It has been standardized most recently in the 20-th century and is now defined in terms of grams (28.35 grams to be precise). The ounce (oz) is a measurement of mass used mostly in UK and the the former British colonies, including the US, UK, Australia, New Zealand, among others. Ounces of vegetable oil to cups conversion table.Ounces to cups of milk conversion table.Ounces of water to cups conversion table.A fluid ounce is 1/32 nd of a quart, and is the amount of water that weighs one ounce. Modern ounce weight and volume measurements, however, come from Britain. Ounce comes from the Roman term “uncia.” An uncia was 1/12 of a Roman copper bar that was used as a tool to measure the length of an inch and the weight of an ounce. For the rest of us mere mortals Fannie Farmer’s standardization was a great service. They just pour in ingredients and their cooking always seems perfect. Prior to this it was common for recipes to use terms like a handful of rice or a generous portion of sugar. It was initiated by Fannie Farmer the director of the Boston Cooking School in 1896, and first appeared in her book “The Boston Cooking School Cook Book”. The standardized measure of a cup is relatively new. 16 fluid olive oil weighs less than a pound, so always use your liquid measuring cups! Quick Conversion Chart Fluid Ounces Other ingredients, however, can vary greatly in their volume to weight ratio. 16 fluid ounces of water is a pint and also weighs a pound. What we sometimes confuse, however, is that weight and volume are two different animals. We were raised to understand that there are 16 ounces in a pound, 16 ounces in a pint, 8 ounces in a cup, etc. One key concept is weight vs volume measurements. In cooking, and especially baking, precise measurements are often the difference between an okay (or worse) result and great cooking. For instance, 1 cup of sugar will be much heavier (more ounces) than 1 cup of rice puffs (less ounces). Depending on what ingredient you’re measuring, there could be different ounces in a cup. While fluid ounces are more a measure of volume (meant to measure liquids), ounces are a measure of weight (meant to measure solids). Fluid ounces are more straight forward than ounces.
