Cake Pan Size & Area Converter
Calculate ingredient scaling multipliers and baking adjustments when converting recipes between different sized round, square, and rectangular cake pans.
Formula
Multiplier = Target Pan Area (cm²) / Source Pan Area (cm²)
Source / method note
Calculated using geometric surface areas (πr² and width × length) and volumetric batter expansion ratios.
Legal / official rate note
For baking optimization. Baking times may vary depending on pan material (metal, glass borcam, silicone) and oven airflow.
Frequently Asked Questions
How do I convert a round cake recipe to a square pan?
Calculate the surface area of both pans and divide the square pan area by the round pan area to find your scaling multiplier.
