About BMI Calculator
Body Mass Index (BMI) is a simple measure of body fat based on your weight relative to your height. It is widely used in health assessments to identify potential risks associated with underweight, overweight, or obesity. BMI is not a perfect measure, as it does not account for muscle mass, bone density, or fat distribution, but it provides a useful general guideline.
•BMI Categories
- < 18.5: Underweight – Possible malnutrition or health risk
- 18.5-24.9: Normal weight – Healthy range for most adults
- 25-29.9: Overweight – Increased risk of cardiovascular issues
- > 30: Obese – High risk of chronic diseases like diabetes, heart disease
•BMI Formula
- BMI = Weight (kg) ÷ Height² (m²)
- BMI = Weight (lbs) ÷ Height² (in²) × 703
- Healthy range: 18.5 – 24.9 BMI
- Average ideal weight corresponds to BMI ≈ 21.7
•Tips & Notes
- BMI is a screening tool, not a diagnostic measure.
- Consider muscle mass and body composition when interpreting results.
- Use BMI alongside other health indicators like waist circumference and lifestyle factors.
- Children and elderly require adjusted BMI interpretation.
