A BMI Calculator is a tool designed to calculate a person's Body Mass Index (BMI), which is a measure used to assess whether an individual has a healthy body weight for a given height. It provides a numerical value based on the ratio of a person's weight to their height.
How the BMI is Interpreted:
The BMI value is categorized into ranges, which help determine if someone is underweight, normal weight, overweight, or obese:
Underweight: BMI less than 18.5
Normal weight: BMI between 18.5 and 24.9
Overweight: BMI between 25 and 29.9
Obesity: BMI 30 or higher
Key Features of a BMI Calculator App:
Input Fields: Users input their height and weight.
Unit Selection: Users can choose between metric (kg/m) or imperial (lbs/in) units.
Instant Calculation: Once the values are entered, the app calculates BMI immediately.
Health Categorization: The result is shown with a health category (e.g., "Normal weight," "Overweight").
Optional Features: Some apps may include additional features like tracking BMI over time, offering tips on healthy living, or suggesting ideal weight ranges based on height.
Limitations:
While BMI provides a general indicator of body weight health, it does not account for factors like muscle mass, bone density, or overall body composition. Therefore, BMI may not always reflect an individual's true health status (e.g., athletes with high muscle mass may have a high BMI but low body fat).
