Pot Size Converter
Use outside or inside measurements consistently. Results are geometric estimates for an ideal cylinder.
The calculation assumes a perfect cylinder: L = π × (diameter ÷ 2)² × height ÷ 1,000. Tapered pots and manufacturer capacities can differ, especially when dimensions are external.
Uses the current ratio and a fixed 0.5 L step (90 rows).

A QUICK WALKTHROUGH
How to use this tool
- Enter diameter and height to estimate cylindrical volume.
- Or enter volume and a height-to-diameter ratio to estimate diameter and height.
- Treat the result as an approximation and compare it with the manufacturer’s internal capacity.
Dimensions to volume
The calculation assumes a perfect cylinder: L = π × (diameter ÷ 2)² × height ÷ 1,000. Tapered pots and manufacturer capacities can differ, especially when dimensions are external.
