1. What is BMI?

Body Mass Index (BMI) is a simple calculation using a person's height and weight. For women, the normal range is typically 18.5–24.9 kg/m². BMI provides a reliable indicator of body fatness for most people.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

Where:

• \( weight \) — Body weight in kilograms
• \( height \) — Height in meters

Explanation: The formula divides weight by the square of height to account for the fact that weight increases with the square of height.

3. Importance of BMI Calculation

Details: BMI is a quick screening tool for weight categories that may lead to health problems. For women, maintaining a BMI in the normal range is associated with lower risks of weight-related diseases.

4. Using the Calculator

Tips: Enter weight in kilograms and height in meters. For accurate results, measure height without shoes and weight with minimal clothing.
