Converting Pan Sizes
If a recipe calls for an 8-inch round pan but you only have a 9x13 rectangular pan, you can't just guess the batter amounts. You must calculate the surface area of both pans to find the correct multiplier.
Common Pan Areas
- 8-inch round: ~50 sq in
- 9-inch round: ~64 sq in
- 8x8 square: 64 sq in
- 9x13 rectangle: 117 sq in
