About this calculator
Enter the pot volume and your serving size. The calculator also shows two reference scenarios, 250 mL and 400 mL; these are examples, not universal starter or main-course portions. The recipe multiplier compares your chosen bowl count with a four-serving recipe.

Formula and variables
n = 1000V ÷ b; n₁ = 1000V ÷ 250; n₂ = 1000V ÷ 400
- V
- Pot volume (L)
- b
- Bowl size (mL)
Reference portions use 250 mL and 400 mL. The entered bowl size controls the main serving estimate; recipe multiplier compares it with four portions.
Frequently asked questions
What do the 250 mL and 400 mL reference servings mean?
They are fixed comparison examples used for the starter and main-course outputs, not universal serving standards. The main servings result uses the bowl size you enter. The recipe multiplier compares that serving count with a four-serving recipe.
