How round pan scaling works
Compare round baking-pan areas to scale batter quantities.
Formula and convention
Scale factor = (new diameter / original diameter)², assuming equal pan depth.A worked example
A 20 cm to 24 cm round pan change gives factor 1.44.
Scope and precision
Area does not determine baking time. Depth, material, batter type, temperature, and safe fill level need separate consideration.
