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.
Usage Guidelines & Tips
- 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.
Frequently Asked Questions
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.
