What is BMI?
Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is BMI = kg/m2 where kg is a person's weight in kilograms and m2 is their height in meters squared. BMI is an inexpensive and easy screening method for weight category—underweight, healthy weight, overweight, and obesity.
How to Use the BMI Calculator
To use the BMI calculator, enter your height in centimeters and your weight in kilograms. Then click the "Calculate BMI" button to see your BMI and the associated weight category. The BMI categories are:
- Underweight: BMI less than 18.5
- Normal weight: BMI 18.5–24.9
- Overweight: BMI 25–29.9
- Obesity: BMI 30 or greater
Importance of BMI
BMI is a useful measure of overweight and obesity. It can provide a rough estimate of whether a person is underweight, of normal weight, overweight, or obese. Maintaining a healthy BMI is important for overall health and can help prevent and control many health conditions.
Limitations of BMI
While BMI is a useful screening tool, it does have some limitations. It does not directly measure body fat, and it does not consider the distribution of fat on the body. Factors such as muscle mass, bone density, and overall body composition can affect BMI results. Therefore, it is important to consider other factors and consult with a healthcare provider for a more comprehensive assessment of health.
