How BMI is calculated

The tool computes BMI = weight(kg) / height(m)^2 locally and maps it to common ranges for underweight/normal/overweight. Data is not uploaded.

BMI is a rough measure and can read high for muscular people, so consider body fat too.
Adult ranges are general; children and the elderly have their own standards.

FAQ

1. What BMI counts as normal?

A common adult standard: 18.5-24 normal, below 18.5 underweight, 24-28 overweight, 28+ obese (bodies vary by organization).

2. Is BMI accurate?

It only estimates from height and weight without separating muscle and fat, so athletes may read high and high-body-fat people low; use it as a reference, not the only basis.
