Baking Recipe Adjustment Calculator

How to calculate Baking pan conversion?

Compute each pan's volume and compare them to determine the scaling factor for your recipe.

Key formula: adjustment_factor = desired_volume ÷ original_volume (where volume = length × width × height).

Using the Baking pan conversion calculator: an example

Example values: original pan 20 × 20 × 5 cm, desired pan 25 × 25 × 6 cm.

Step-by-step calculation:

1. Original volume = 20 cm × 20 cm × 5 cm = 2,000 cm³.
2. Desired volume = 25 cm × 25 cm × 6 cm = 3,750 cm³.
3. Adjustment factor = 3,750 ÷ 2,000 = 1.875 — multiply all ingredient quantities by this factor.
4. Example: 200 g flour × 1.875 = 375 g flour; scale other ingredients the same way.

Frequently Asked Questions

Will baking time change?

Yes. Larger or deeper volumes often require slightly longer baking; check doneness and adjust time or temperature modestly to avoid overbaking.

Does pan shape matter?

Shape influences surface area and heat distribution, but volume-based scaling is still appropriate; be prepared to adjust baking time for different shapes.

How should I scale frostings or toppings?

Frostings scale more with surface area than volume. Increase quantities proportionally but adjust by eye for desired coverage and thickness.
