Kitchen Tools & Baking Calculators
Our free kitchen tools are designed to make everyday cooking and baking conversions easier. Convert cups and grams using ingredient-specific values, estimate oven-to-air-fryer settings, work between grams and teaspoons, or resize a cake recipe for a different tin.
Where a conversion depends on ingredient density, tin dimensions or appliance performance, the calculator uses the information you enter rather than treating every ingredient or recipe as identical. Results are intended as practical kitchen guidance, so always follow recipe, packaging and appliance instructions where they are more specific.
Cups to Grams & Grams to Cups Converter
Convert US, UK, and Metric cup measurements to exact grams for flour, sugar, butter, oats, and 20+ baking staples using real density data.
Air Fryer Calculator
Convert oven temperatures and cooking times for your air fryer. Optimised for UK home cooks using fan or conventional ovens.
Grams to Teaspoons Converter
Convert grams to teaspoons for flour, sugar, butter, salt, and more. Choose your ingredient for quick, accurate UK cooking and baking conversions.
Cake Tin Conversion Calculator
Resize cake recipes for different round, square, loaf and rectangular tins in cm or inches.
Grams to Ounces Converter UK
Convert grams to ounces or ounces to grams instantly for UK cooking and baking.
Which Kitchen Tool Should I Use?
Select the calculator that matches your current recipe challenge.
Cups to Grams Converter
Use this when a recipe gives an ingredient in cups but you want to measure it in grams, or when you need to convert grams back to cups. Ingredient selection matters because a cup of flour does not weigh the same as a cup of sugar.
Air Fryer Calculator
Use this when adapting an oven recipe for an air fryer. It provides a practical starting estimate for temperature and cooking time while allowing for fan or conventional oven settings.
Grams to Teaspoons Converter
Useful for smaller ingredient quantities where a recipe needs grams converted to teaspoons or teaspoons converted back to grams. Values should remain ingredient-specific rather than using one universal conversion.
Cake Tin Conversion Calculator
Use this when changing the size or shape of a cake tin. It calculates a recipe multiplier based on the original and target tins instead of guessing from diameter alone.
Grams to Ounces Converter UK
Use this to convert weight measurements between grams and ounces. The tool handles both directions instantly and displays decimal conversions for accurate cooking and baking.
How Our Kitchen Conversions Work
Not every kitchen conversion is a simple fixed equation. Grams measure weight, while cups and teaspoons measure volume, so the same volume can weigh very differently depending on the ingredient. Our ingredient-based converters account for that distinction rather than applying one value to everything.
Cake tin conversions use the dimensions and shape of the tins to estimate how a recipe should be scaled. Air fryer conversions are different again: appliance power, food thickness and basket loading can change actual cooking time, so those results should be treated as starting points rather than guarantees.
Where a recipe, food package or appliance manufacturer gives more specific instructions, follow those instructions first.
A quick note on accuracy
Kitchen conversions are estimates unless the relationship is mathematically exact. For baking, weighing ingredients in grams is usually the most consistent option. For cooking-time tools, check food as it cooks and follow relevant food-safety and appliance guidance.
Kitchen Tools FAQs
Are the kitchen calculators free to use?
Yes. The tools on Our British Kitchen can be used directly in the browser without payment.
Do these tools use UK measurements?
The tools are designed for UK cooks and bakers, with metric measurements and British cooking terminology used where appropriate.
Why do cups-to-grams conversions change by ingredient?
A cup measures volume, while grams measure mass. Ingredients have different densities, so the same cup volume can weigh different amounts depending on what is being measured.
Are air fryer cooking times exact?
No. Air fryer results are starting estimates because models, food thickness, quantity and starting temperature vary. Users should check food during cooking and follow packaging or appliance instructions where applicable.
