How to measure

1. Measure outer diameter d₁ across the widest point.
2. Measure inner diameter d₂ (set 0 for solid slabs).
3. Measure height (thickness) h — typical units: mm, cm or m.
4. Choose material density to estimate weight.

Note: Inputs accept decimals. If diameters are in cm/mm, the calculator converts to meters for final values.
