Recipe multiplier—
This compares pan surface area. Keep pan depth reasonably similar for the best result.
How it works
Compares the surface area of the original and new tins. Multiply every ingredient quantity by the resulting factor. Similar pan depths are important because very different depths can change baking time and heat transfer.
Cooking conversions are practical estimates. Ingredient brands, packing methods, cookware and appliances can affect real-world results.
CALCULATOR GUIDE
How baking pan conversion works
Different pan shapes and sizes change the available baking area or volume. The calculator compares the original and replacement pans so you can scale a recipe more sensibly.
Baking depth and cooking time can still change even when pan capacity is similar, so use the conversion as a guide and monitor the bake.
