About BMI Calculator
BMI (Body Mass Index) is the standard screening number for healthy weight: weight (kg) divided by height (m) squared. This tool computes your BMI in both metric and South-Asian-friendly units, shows the WHO category (underweight, normal, overweight, obese) and the exact weight range for your height.
BMI is a screening tool, not a diagnosis — athletes and older adults can be misclassified. For a personal assessment consult a doctor or nutritionist.
How to use — step by step
- Choose metric (kg + cm) or imperial (ft/in + lb) units.
- Enter your height and weight.
- Press Calculate BMI — the index, category and healthy range show instantly.
Frequently asked questions
QHow is BMI calculated?
BMI = weight (kg) ÷ height² (m²). Example: 65 kg at 1.70 m → 22.5 (normal).
QWhat is a healthy BMI?
The WHO range is 18.5–24.9. Many South-Asian health guidelines suggest a tighter upper bound (about 23) for people of Nepali ethnicity — treat categories as screening hints rather than verdicts.
