Understanding Measurements
Metric vs. Imperial Units of Measurement
Before we dive into how many cups are in 28 ounces, let’s first understand the two main measurement systems used worldwide: metric and imperial.
The metric system is based on units of ten and is widely used throughout the world, except for a few countries like the United States. On the other hand, the imperial system uses more complex units that vary depending on what you’re measuring.
US Customary System
In the United States, we use the US customary system, which is a variation of the imperial system. It includes units such as inches, feet, pounds, quarts, gallons, and fluid ounces. In cooking and baking specifically, we use fluid ounces and cups to measure liquids or ingredients with similar densities.
Fluid Ounces and Cups
A fluid ounce (fl oz) is a unit of volume measurement equal to approximately 29.5735 milliliters (ml). In contrast, a cup is a standard unit of measurement equivalent to eight fluid ounces or approximately 236.59 ml.
Knowing these basic measurements will help us convert 28 ounces to cups accurately in our next section.
Conversion Factors and Formulas
Converting Ounces to Cups
To convert ounces to cups, we need to know the conversion factor. One cup equals eight fluid ounces, so the conversion factor is 1:8. To convert a given number of ounces to cups, divide it by eight. For example, if you have 28 fluid ounces of liquid that you want to measure in cups, divide 28 by 8. The answer is 3.5, which means that 28 fluid ounces are equal to 3 and a half cups.
Using Formulas for Accuracy
If you’re dealing with a recipe that requires precise measurements or conversions between different measurement units, using formulas can be helpful. The formula for converting fluid ounces to cups is:
Number of Cups = Number of Fluid Ounces ÷ 8
Let’s take an example where we have to convert 40 fluid ounces into cups. Using the above formula,
Number of Cups = 40 / 8 = 5
So, 40 fluid ounces are equivalent to five cups.
Using formulas is handy when dealing with larger quantities or complicated recipes that require multiple conversions. It also ensures accuracy and consistency in your cooking or baking.
Standard Cup Sizes
Cups are a standard unit of measurement in cooking and baking, commonly used to measure liquid or dry ingredients. In the United States, two types of cup measurements are prevalent – US customary cups and metric cups.
US Customary Cups
US customary cups are used for measuring both liquid and dry ingredients. One US customary cup is equivalent to 8 fluid ounces or 16 tablespoons. The following are the most common cup sizes used in the US:
- 1/4 cup (2 fluid ounces)
- 1/3 cup (2.67 fluid ounces)
- 1/2 cup (4 fluid ounces)
- 1 cup (8 fluid ounces)
- 2 cups (16 fluid ounces)
Metric Cups
Metric cups are based on the International System of Units (SI) and are used around the world. Unlike US customary cups, metric cups are only used to measure liquids. One metric cup is equivalent to 250 milliliters or approximately 8.45 fluid ounces. The following are some of the most common metric cup sizes:
- 1/4 metric cup (62.5 milliliters)
- 1/3 metric cup (83.33 milliliters)
- 1/2 metric cup (125 milliliters)
- 1 metric cup (250 milliliters)
- 2 metric cups (500 milliliters)
It’s essential to note that when converting between US customary cups and metric cups, there may be slight variations due to rounding errors in conversions between different systems of measurements.
Knowing the standard cup sizes can help you accurately convert measurements between different recipes, ensuring your dishes turn out perfectly every time!

Measuring Ingredients by Weight
As any experienced baker will tell you, measuring ingredients accurately is key to achieving consistent and delicious results. While measuring cups can be convenient for some recipes, they are not always precise. The weight of an ingredient can vary depending on factors such as humidity and packing density. This is why measuring ingredients by weight is more accurate than volume measurements like cups or ounces.
Why Measuring Ingredients by Weight is More Accurate
When you measure flour using a cup, the amount of flour you scoop into the cup can vary depending on how tightly it’s packed or how much air has been incorporated. This makes it difficult to achieve consistency in your baking. On the other hand, when you measure flour by weight, you remove this variability from the equation. A cup of flour can weigh anywhere from 120g to 150g, but if you use a kitchen scale to weigh out 125g each time, you’ll get consistent results.
Measuring ingredients by weight also allows for easier scaling of recipes. If a recipe calls for 300g of flour, it’s easy to double or halve that amount accurately with a kitchen scale. Additionally, many professional bakers and pastry chefs rely solely on weight measurements in their recipes.
Converting Ounces or Cups to Grams
If a recipe uses ounces or cups as its unit of measurement, converting these units to grams is straightforward. For example, one cup of all-purpose flour weighs approximately 125g. To convert 28 ounces to grams, simply multiply the number of ounces by 28.35 (the conversion factor between ounces and grams). In this case, 28 ounces would be equivalent to 793.8g.
By measuring ingredients by weight instead of volume, you’ll ensure accuracy and consistency in your baking every time. So next time you’re tackling a new recipe, consider investing in a kitchen scale – your taste buds will thank you!
Tips for Accurate Measurement
When it comes to cooking and baking, accurate measurements are crucial to achieving the desired results. Here are some tips to ensure you get it right every time:
Tips for Ensuring Accurate Measurement when Using Cups or Scales
1. Use the Right Measuring Tools
When measuring dry ingredients, use dry measuring cups, and when measuring liquids, use liquid measuring cups. It’s also important to use the correct size cup specified in the recipe.
For weighing ingredients, invest in a digital kitchen scale that can measure both ounces and grams accurately.
2. Level Off Ingredients
Whether using cups or scales, always level off your ingredients to avoid over or under-measuring. Use a straight edge like a knife or spatula to remove any excess ingredients from the top of the cup or bowl.
3. Measure in Good Light
Ensure that you have enough light while measuring ingredients as this will help you see the markings on your measuring tools more clearly.
Common Mistakes People Make When Measuring Ingredients
1. Scooping Flour Directly from the Bag
Scooping flour directly from the bag can result in an incorrect measurement as it can be compacted during storage. Instead, spoon flour into your measuring cup and then level it off.
2. Estimating Measurements
It’s easy to estimate measurements when you’re short on time; however, this can lead to inaccurate results and ultimately ruin your dish.
3. Not Compensating for Humidity
Humidity affects dry ingredients’ weight and volume, so if you’re baking on a humid day, be sure to compensate by adding more flour than usual or reducing the liquid portion of the recipe.
By following these tips and avoiding common mistakes, you’ll become a pro at accurate ingredient measurement in no time!
