16 ToolsBMI & Body Fat Calculator
Calculate your Body Mass Index (BMI) and estimated Body Fat % using Indian/Asian health standards.
For the Indian population, the WHO and ICMR recommend lower BMI thresholds due to higher metabolic risks. A healthy Indian BMI is 18.5–22.9 kg/m², overweight is 23–24.9 kg/m², and obese is ≥25 kg/m².
