How to Use the BMI Calculator
Enter your height and weight using either metric (cm/kg) or imperial (ft/in/lbs) units. The calculator instantly computes your BMI and shows your weight category: underweight, normal, overweight, or obese. You also get a visual indicator showing where your BMI falls on the scale.
Understanding BMI
Body Mass Index (BMI) is a simple measurement that uses your height and weight to estimate body fat. While it is not a direct measure of health, it provides a useful starting point for understanding your weight status. A BMI between 18.5 and 24.9 is considered healthy for most adults. Scores below or above this range may indicate potential health risks worth discussing with a healthcare provider.
Step-by-Step Guide
- Select your preferred unit system (metric or imperial)
- Enter your height
- Enter your weight
- Your BMI score and category appear instantly
- Use the information to track changes over time
Limitations to Keep in Mind
BMI does not distinguish between muscle and fat. Athletes and bodybuilders may have a high BMI despite being very fit. Elderly individuals may have normal BMI but low muscle mass. Use BMI as a general guideline, not a definitive health diagnosis. Always consult a healthcare professional for personalized medical advice.
