Free Health Calculators That
Use Indian Standards
Most health calculators only show WHO values. We add ICMR - the standard Indian doctors reference - so you see the full story. Where applicable, results are shown against both Indian and WHO standards.

Indians often carry more visceral fat and a higher body-fat percentage at the same BMI. That is one reason Indian and Asian BMI action points start at BMI 23 rather than 25.
The Real Risk
India has an estimated 101 million people living with diabetes. Indians often develop type 2 diabetes at younger ages and lower BMI or waist sizes than Western populations.
What We Do Differently
Every calculator uses ICMR guidelines as the primary result, with the WHO standard shown alongside. You see both - and understand why they differ.
