Baking Pan Converter
A pan size converter calculates exactly how to scale recipes when switching between baking pan sizes. Volume — not diameter — is what matters. A 9-inch (23 cm) round pan holds about 1.3× more batter than an 8-inch (20 cm) round, meaning you need roughly 30% more of every ingredient.
Common Uses for This Conversion
Substituting pans you already own, converting American inch measurements to European centimeters, dividing batter across multiple smaller pans, adjusting baking time alongside ingredient quantities, and scaling recipes for different numbers of servings.
💡Did You Know?
Volume scales with the square of the radius. Switching from a 20 cm to a 23 cm round pan increases volume by (23/20)² ≈ 1.32 — that's 32% more batter, not the 15% the diameter ratio alone suggests. Always scale by volume for accurate results.
