Conicity Index (Valdez 1991): waist (m) / (0.109 × √(weight (kg) / height (m))); a higher value marks greater central adiposity.

Example
- Waist circumference
- 100 cm
- Weight
- 80 kg
- Height
- 175 cm
Result: Conicity Index 1.36 — higher values indicate greater central adiposity.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Index
- CI = waist(m) / (0.109 x sqrt(weight(kg) / height(m))). Models the body as a double cone; higher values indicate greater central adiposity. An index, not a diagnostic test.
