Understanding Body Mass Index (BMI)
Body Mass Index (BMI) is a widely used measurement to gauge whether your weight is healthy in proportion to your height. It's a simple screening tool to identify potential weight problems for adults.
The Formula: BMI is calculated as `weight (kg) / [height (m)]^2` or `(weight (lbs) / [height (in)]^2) * 703`. Our tool handles both metric and imperial units.
Interpreting Results:
- Below 18.5: Underweight
- 18.5 – 24.9: Healthy Weight
- 25.0 – 29.9: Overweight
- 30.0 and Above: Obese
