BMI Calculator — Body Mass Index with Indian Standards
CalculatorCalculate your Body Mass Index (BMI) with both international (WHO) and India-specific cutoffs. Research shows Asian populations, including Indians, face metabolic risks at lower BMI thresholds — overweight is classified at BMI ≥23 (not ≥25) and obese at ≥27.5 (not ≥30) for Indians. Supports metric (kg/cm) and imperial (lbs/in).

Expert Note — India 2026
The Indian Council of Medical Research (ICMR) 2024 guidelines recommend using Asian-specific BMI cutoffs: <18.5 underweight, 18.5–22.9 normal, 23–24.9 overweight, ≥25 obese (Grade I), ≥30 obese (Grade II). Standard WHO cutoffs (overweight at ≥25, obese at ≥30) underestimate cardiovascular and type-2 diabetes risk in South Asian populations.

Frequently Asked Questions
Is BMI accurate for Indians?
Standard BMI thresholds underestimate risk for Indians. Indian guidelines suggest overweight starts at BMI 23+ and obesity at 25+, compared to the global standard of 25 and 30 respectively.
How is BMI calculated?
BMI = Weight (kg) ÷ Height² (m²). For imperial: BMI = 703 × Weight (lbs) ÷ Height² (inches²).
What BMI is considered obese in India?
For Indians and South Asians, BMI ≥25 is classified as Grade I obesity and ≥30 as Grade II obesity, per ICMR 2024 guidelines. Standard WHO classifies obesity at BMI ≥30.
