BMI Calculator

How to Use

1. Enter your height in centimeters and weight in kilograms.
2. Your BMI and weight category are calculated instantly.

Calculation Method

BMI (Body Mass Index) is calculated as weight (kg) ÷ height (m)². This tool uses Asian-specific WHO thresholds, which are stricter than the standard Western thresholds: under 18.5 is underweight, 18.5–22.9 is normal, 23–24.9 is overweight, 25–29.9 is obese, and 30 or above is severely obese.

Common Uses

• Getting a quick, general sense of whether your weight is in a healthy range.
• Tracking BMI changes over time alongside a fitness or health goal.

BMI does not account for muscle mass, bone density, or body composition, so it should be treated as a general indicator, not a diagnosis. Consult a healthcare professional for personalized advice.
