Caster sugar dissolves faster, which is ideal for air fryer baking. If using granulated sugar, pulse it briefly in a blender to mimic caster sugar’s fine texture.” } }, { “@type”: “Question”, “name”: “How do I convert 20g of caster sugar to cups?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “20g of caster sugar is roughly 0.1 UK cups or 0.08 US cups. However, measuring by weight (grams or ounces) is far more accurate for baking. Cups can vary based on how tightly the sugar is packed, so a scale is recommended.” } }, { “@type”: “Question”, “name”: “Why does my air fryer bake differently with 20g of sugar versus ounces?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Air fryers rely on precise measurements for even cooking. If your conversion from 20g to ounces is slightly off, it can affect browning and texture. Always use the most accurate measurement possible, whether in grams or ounces, for consistent results.” } }, { “@type”: “Question”, “name”: “Is 20g of caster sugar the same as icing sugar in ounces?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “No, icing sugar is lighter and fluffier than caster sugar. While 20g of caster sugar equals 0.71 ounces, the same weight of icing sugar will take up more volume. Always check the type of sugar specified in your recipe for the best results.” } } ] }

20 grams of caster sugar is equivalent to approximately 0.71 ounces. This conversion is essential for precise baking, especially when using an air fryer where measurements can make or break a recipe. Whether you're whipping up cakes or cookies, knowing how to convert grams to ounces ensures consistent results every time.
Why accurate sugar measurements matter in air fryer baking
Air fryers cook food faster and more evenly than conventional ovens, but this also means small measurement errors can have a big impact. Too much sugar can cause over-browning or even burning, while too little can leave your bakes tasting bland. By converting 20g of caster sugar to ounces accurately, you’ll achieve the perfect balance of sweetness and texture.

How to measure 20g of caster sugar without scales
Not everyone has a kitchen scale handy, but there are still ways to measure 20g of caster sugar accurately. One tablespoon of caster sugar typically weighs around 12.5g, so 1.5 tablespoons will give you roughly 20g. Alternatively, a standard UK teaspoon holds about 4.2g, meaning just under 5 teaspoons will do the trick.
If you’re working with ounces, remember that 0.71 ounces is slightly less than three-quarters of an ounce. A digital scale is always the most precise option, but these approximations work well in a pinch. For more measurement hacks, explore our cake recipes section, where precision is key.
Common mistakes when converting grams to ounces
One of the biggest mistakes people make is confusing fluid ounces with weight ounces. Caster sugar should always be measured by weight, not volume. Another pitfall is rounding too early—0.71 ounces is more precise than 0.7, especially in delicate bakes. Always double-check your conversions to avoid disappointment.
Best air fryer recipes using 20g of caster sugar
Many air fryer recipes call for small amounts of sugar, like 20g, to achieve the perfect sweetness without overdoing it. For example, our cookie recipes often use this amount to create crisp yet tender treats. Caster sugar dissolves quickly, making it ideal for air fryer baking where even distribution is crucial.
Another great option is air fryer sponge cakes, where 20g of caster sugar provides just enough sweetness without weighing the batter down. Pair it with our air fryer cleaner tips to keep your appliance in top condition after baking. A clean air fryer ensures even cooking and better-tasting results every time.
Storing caster sugar for air fryer baking
To keep your caster sugar fresh and ready for precise measurements, store it in an airtight container in a cool, dry place. Humidity can cause clumping, which makes measuring 20g accurately more difficult. Proper storage ensures your sugar stays free-flowing and easy to measure, whether you’re using grams or ounces.
