Body Mass Index Calculator
This calculator helps you determine your Body Mass Index (BMI), a widely used indicator to classify underweight, normal weight, overweight, and obesity based on your height and weight. It is a simple and effective tool for assessing general body health and risk of chronic diseases.
BMI Calculator – Weight Status Indicator
Body Mass Index Formula
$$\text{BMI} = \frac{W}{H^2}$$
Where:
- $$W$$ = Weight in kilograms (kg)
- $$H$$ = Height in meters (m)ge (years)
BMI is a quick screening tool used globally to categorize body weight:
- Underweight: BMI < 18.5
- Normal weight: 18.5 ≤ BMI < 24.9
- Overweight: 25 ≤ BMI < 29.9
- Obese (Class I): 30 ≤ BMI < 34.9
- Obese (Class II): 35 ≤ BMI < 39.9
- Extreme obesity (Class III): BMI ≥ 40
Although BMI doesn’t distinguish between muscle and fat, it’s still a helpful measure for general population health.
