01 / HOW TO USE IT
From inputs to a usable kitchen figure
- 01
Choose each pan shape and enter its internal dimensions.
- 02
Enter the number of source pans and target pans available.
- 03
Calculate the area factor and batch coverage, then verify depth and equipment limits.
02 / WHEN IT HELPS
Useful for everyday production planning
- Moving a bake from hotel pans to sheet pans
- Estimating how many smaller pans a batch will fill
- Scaling a batch to a fixed number of target pans
03 / THE WORKING MODEL
Assumptions and limitations
Assumptions
- All pans are filled to the same depth.
- Entered dimensions are internal usable dimensions in the same unit.
- Capacity changes in direct proportion to pan surface area.
Check before using
- Wall slope, corners, stated pan sizes, fill headroom, batter behaviour, and actual volume can differ.
- Bake or chill time may change with shape, material, airflow, and load.
- Never exceed manufacturer equipment or pan capacity guidance.
04 / QUICK ANSWERS
Frequently asked questions
Why does the calculator use surface area?
At equal fill depth, volume is proportional to the pan surface area.
Can I convert round pans to rectangular pans?
Yes. Each pan area is calculated from its selected shape before they are compared.
Will the cooking time stay the same?
Not necessarily. Pan material, shape, airflow, product depth, and equipment load can all change timing.
