9 Inch Round to 9x5 Loaf Pan Converter
Area-based volume scaling for round, square, loaf, Bundt, and 9x13 sheet pans.
Pan Geometry & Oven Science Guide
A 9-inch round pan holds 8 cups of volume (63.6 sq in). A 9x5-inch loaf pan also holds 8 cups of volume (45 sq in). They have equivalent liquid capacities.
Quick bread batters (banana bread, zucchini bread, pumpkin loaf) can be baked in either pan. In the 9-inch round, it bakes as a snacking cake in 25–30 minutes; in the 9x5 loaf pan, it bakes in 50–60 minutes at 325°F.
Standard Cake Pan Surface Area & Volume Guide
Surface area dictates batter depth, while volume dictates maximum safe capacity.
