How to use the mortgage calculator?
A BMI calculator is a tool used to compute a person's Body Mass Index (BMI).
- BMI stands for Body Mass Index.
- It's a numerical value derived from a person's weight and height.
- It's used as a simple, inexpensive screening method to estimate body fatness and categorize weight status (underweight, healthy weight, overweight, or obese).
How does a BMI Calculator Work?
- It takes your height and weight as input.
- It applies a standard mathematical formula to calculate your BMI score.
The calculator then typically displays the resulting BMI number and often tells you which weight category that number falls into.
What are the BMI Categories (for adults)?
- Underweight: BMI less than 18.5
- Healthy: BMI 18.5 to 24.9
- Overweight: BMI 25 to 29.9
- Obese: BMI 30 or greater (often further subdivided into classes)
Important Limitations:
- Doesn't Distinguish Fat from Muscle: BMI doesn't differentiate between weight from muscle and weight from fat. Very muscular individuals (like athletes) might have a high BMI but low body fat percentage.
- Doesn't Account for Body Composition: It doesn't consider factors like bone density, body frame size, or fat distribution.
- Other Factors: It doesn't account for age, sex, or ethnicity, which can influence the relationship between BMI and health risk.
- Screening, Not Diagnostic: BMI is a screening tool, not a diagnostic tool. It doesn't definitively measure health or body fat percentage. A healthcare provider should interpret BMI results in the context of other health information.
