About the BMI Calculator
Body Mass Index (BMI) is a quick screening number that compares your weight to your height — weight in kilograms divided by height in metres squared. A BMI of 18.5–24.9 is generally considered the healthy range, 25–29.9 overweight, and 30 or above obese. Because BMI can’t tell muscle from fat, very muscular or very lean people can read misleadingly high or low, so treat it as a general guide rather than a diagnosis. It’s most useful for spotting trends over time and as a starting point for a conversation with a healthcare provider.
