Why use a free kitchen calculator?

🫕

Air fryer conversions — why they matter

Air fryers circulate heat far more efficiently than conventional ovens. Without adjusting temperature and time, food can easily overcook. Our oven to air fryer converter applies the standard −25°F / −20% time rule — plus brand-specific adjustments for Ninja, Cosori, Philips and more — so you always get perfectly cooked food on the first try.

🥚

Egg substitutes — which one to use

Not all egg substitutes work the same way. Applesauce is best for cakes and muffins. Flax egg is best for cookies and quick breads. Aquafaba is the only option for meringues. Our egg substitute calculator and vegan egg substitute calculator give personalised recommendations for any recipe in seconds.

⚖️

Grams vs cups — why it matters for baking

A cup of flour can weigh anywhere from 100g (sifted) to 155g (scooped directly) — a 55% variation from the same measuring cup. Our grams to cups calculator covers 50+ ingredients with US, Metric and UK cup standards. For tablespoon conversions, the tablespoons to grams converter handles any ingredient instantly.

FAQ

Kitchen calculator questions

Common questions about our free kitchen tools — answered below.

Reduce the temperature by 25°F (about 15°C) and reduce cooking time by 20%. So a recipe at 400°F for 30 minutes becomes 375°F for 24 minutes. Always check food 2–3 minutes before the timer ends, as every air fryer model differs slightly. Use the free air fryer conversion calculator for instant results with brand-specific adjustments.
It depends on the recipe. For cakes and muffins: unsweetened applesauce (¼ cup = 1 egg). For cookies: flax egg (1 tbsp ground flaxseed + 3 tbsp water). For light sponge cakes: aquafaba (3 tbsp = 1 egg). For meringues: aquafaba only. Use our egg substitute for baking calculator or the vegan egg substitute calculator for personalised recommendations.
It depends on the ingredient. 1 tablespoon of water = 15g. Table salt = 18g. Butter = 14g. Honey = 21g. Sugar = 12g. Flour = 8g. Different ingredients have different densities, so there's no single answer. Use the tablespoons to grams converter to get the exact weight for any ingredient instantly.
A cup of all-purpose flour = 125g. A cup of sugar = 200g. A cup of butter = 227g. A cup of water = 237g. The gram weight varies by ingredient and also by cup standard — a US cup is 236.6ml, a Metric cup (Australia, Canada) is 250ml, and a UK cup is 284ml. Use the grams to cups calculator for 50+ ingredients with all cup standards.
It depends on your glass size. Using a standard 250ml glass: 1 litre = 4 glasses. With a 200ml glass: 1 litre = 5 glasses. With a 300ml glass: 1 litre = 3.33 glasses. The daily recommended intake (2 litres) = 8 standard 250ml glasses. Use the glasses of water in a litre calculator for any glass size.
Crystal shape and size determine how densely salt packs into a spoon. Table salt has tiny cubic crystals that pack tightly — 18g per tablespoon. Diamond Crystal kosher salt has large, hollow pyramid-shaped flakes that trap air — only 8.4g per tablespoon. Morton kosher salt sits in between at 14.4g. This is why substituting by volume rather than weight changes the saltiness of a dish. Use the salt grams calculator for all 8 salt types.
