Brownies and dense cakes?

Fill 3/4 to nearly full — dense batters don't rise as much. Cheesecakes can fill nearly to the top.

How do I measure unusual pans?

Fill with water from a measuring cup. Pour to the rim or to your fill mark.

What about bundt pans?

They're tricky — interior tube changes geometry. Most 10-cup bundt holds 10 cups full = 6.5 cups batter. Use water test.

Cup conversion factors?

1 in³ = 16.387 mL = 0.0693 US cups. Loaf 9×5×3 = 135 in³ ≈ 9.4 cups full.

Step-by-step

Area (round) = 63.62 in².
Volume = area × depth = 127.23 in³.
Convert: in³ × 16.387 = 2,085.0 mL = 8.813 cups.
2/3-fill rule for batter: 5.88 cups.

About this calculator

Cakes rise 30-50% during baking, so most cake recipes call for 2/3-full pans. A 9" × 2" round holds ~10.2 cups total, batter fill ~6.8 cups. Comparing your recipe's batter yield to pan capacity tells you if it fits. Loaf pans: standard "9×5" is 8 cups full, 5.3 cups for batter — that's why most quick breads call for 9×5 specifically. For pans you don't recognize, fill with water and measure directly to verify.
