Baking Pan in Recipe
Volume: 1.54 cups
Your Baking Pan
Volume: 4.20 cups
Pans' Volume Ratio
2.72
Multiply all recipe ingredients by this ratio to adjust for your pan size. For example, if the ratio is 2.72, use 272% of each ingredient amount.
How to Use the Cake Pans Converter
Converting cake recipes between different pan sizes is essential when you don't have the exact pan specified in a recipe. Our calculator makes this process simple by calculating the volume ratio between two pans, which tells you exactly how much to multiply each ingredient.
Step-by-Step Instructions
- Enter the recipe pan dimensions - Select the shape (round or rectangular), enter the diameter (for round) or length and width (for rectangular), and the height
- Enter your pan dimensions - Select your pan's shape and enter its dimensions in the same way
- Get the volume ratio - The calculator automatically calculates the ratio between the two pan volumes
- Multiply ingredients - Multiply all recipe ingredient amounts by the volume ratio to adjust for your pan size
- For example, if the ratio is 2.72, use 272% of each ingredient (multiply by 2.72)
Volume Calculation Formulas
Round Pan Volume:
Volume = π × (diameter/2)² × height
This is the volume of a cylinder
Rectangular/Square Pan Volume:
Volume = length × width × height
This is the volume of a rectangular prism
Standard Baking Pan Sizes
| Pan Dimensions | Volume (cups) | Volume (L) |
|---|---|---|
| Round / Springform | — | — |
| 6 × 2 inches | 4 cups | 0.9 L |
| 8 × 2 inches | 7 cups | 1.6 L |
| 9 × 2 inches | 9 cups | 2.1 L |
| 10 × 2 inches | 11 cups | 2.5 L |
| Rectangular | — | — |
| 11 × 7 × 2 inches | 10.5 cups | 2.5 L |
| 13 × 9 × 2 inches | 16 cups | 3.8 L |
Note: Actual volumes may vary slightly. Most recipes fill pans to 1/2-2/3 capacity to prevent overflow.
How to Adjust Baking Time for Different Size Pans
While the volume ratio tells you how much to adjust ingredients, baking time doesn't change proportionally. Here are important guidelines for adjusting baking times:
- • Expect longer baking times
- • Time increase is usually less than the volume ratio
- • Check for doneness more frequently
- • Taller cakes need significantly more time
- • Baking time may be shorter
- • Check for doneness earlier than recipe time
- • Shallower pans bake faster
- • Monitor closely to avoid overbaking
Important: Always use a cake tester, toothpick, or skewer to check if your cake is done. Insert it into the center - if it comes out clean (or with a few moist crumbs), the cake is ready. Don't rely solely on time estimates when using a different pan size.
Conversion Examples
Recipe Pan: 6" round × 2" high
Your Pan: 7" × 11" × 2" rectangular
Calculation:
- Recipe volume: π × (3)² × 2 ≈ 56.5 in³
- Your volume: 7 × 11 × 2 = 154 in³
- Ratio: 154 ÷ 56.5 ≈ 2.72
Result: Multiply all ingredients by 2.72
Recipe Pan: 8" round × 2" high
Your Pan: 9" round × 2" high
Calculation:
- Recipe volume: π × (4)² × 2 ≈ 100.5 in³
- Your volume: π × (4.5)² × 2 ≈ 127.2 in³
- Ratio: 127.2 ÷ 100.5 ≈ 1.27
Result: Multiply all ingredients by 1.27
