ABSI Calculator

The ABSI Calculator determines A Body Shape Index (ABSI), a body composition metric that evaluates abdominal obesity relative to height and weight. Unlike BMI, ABSI incorporates waist circumference to better estimate health risks associated with central fat distribution.

This calculator also computes the ABSI z-score, which compares your ABSI value to population averages based on sex and age. A positive z-score suggests higher-than-average risk, while a negative score indicates lower-than-average risk.

The tool supports multiple units for height, weight, and waist circumference, automatically converting them into standard metric values before calculation.
