2.5 cups of butter equals 20 ounces (or 566 grams). This conversion is essential for air fryer recipes, where precise measurements can make or break your dish. Whether you're whipping up cookies, cakes, or savoury dishes, knowing how to convert cups to ounces ensures perfect results every time.
Butter is a staple in many air fryer recipes, from flaky pastries to crispy coatings. Measuring it accurately is crucial, especially since air fryers cook food faster and more evenly than conventional ovens. A slight miscalculation can lead to dry or overly greasy results, so getting the conversion right matters.
In the UK, butter is often sold in blocks measured in grams, but many recipes—especially those from the US—use cups. This can cause confusion, but once you know that 1 cup of butter equals 8 ounces (227 grams), conversions become straightforward.

Air fryers rely on hot air circulation, meaning ingredient ratios must be precise. Too much butter can lead to excessive browning or even smoking, while too little might leave your dish dry. If you're adapting a traditional recipe for the air fryer, always double-check your measurements.
To convert 2.5 cups of butter to ounces, multiply the number of cups by 8 (since 1 cup = 8 ounces). This gives you 20 ounces. If your butter comes in sticks, note that one standard stick is typically 4 ounces, so you'd need 5 sticks for 2.5 cups.
For those using a kitchen scale, 20 ounces is roughly 566 grams. This method is often more reliable than cup measurements, as butter density can vary slightly. If you're exploring new recipes, our recipe collection has plenty of ideas to try.
One frequent error is using melted butter instead of solid butter when measuring by volume. Always use softened (but not melted) butter for cup measurements. Another pitfall is packing butter into the cup, which can lead to using more than needed.
In the UK, butter is typically sold in 250g blocks, which is slightly less than 1 cup (8.8 ounces). For 2.5 cups (20 ounces), you'd need about 567 grams—just over two UK blocks. If you're baking a classic air fryer cake, this conversion ensures perfect texture.
Remember that European butter has a higher fat content than American butter, which can slightly affect results. Adjustments might be needed for ultra-precise recipes, but for most home cooking, the difference is negligible.
If you don't have a scale, use the markings on butter wrappers or a standard measuring cup. For 2.5 cups, fill a 1-cup measure twice and a ½-cup measure once. Level off the top with a knife for accuracy.
From buttery biscuits to golden shortbread, many air fryer recipes call for generous amounts of butter. When working with 20 ounces (2.5 cups), ensure even distribution for consistent cooking. For savoury dishes like air fryer potatoes, melted butter helps achieve crispiness.
Too much butter can cause smoke in the air fryer, so always monitor cooking progress. If you notice excess grease, dab it with a paper towel mid-cook. For cleaning tips, visit our guide on keeping your air fryer spotless.
If your recipe doesn't use the full 2.5 cups, wrap leftover butter tightly in foil or cling film. Store it in the fridge for up to a month or freeze for longer shelf life. Always bring butter to room temperature before using it in air fryer recipes for even mixing.
