1. What is BMI?

Body Mass Index (BMI) is a simple calculation using a person's height and weight. For older adults, BMI ranges may be interpreted differently to account for age-related changes.

2. How Does the Calculator Work?

The calculator uses the BMI equation:

Where:

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

Explanation: The equation calculates body mass divided by the square of height to estimate body fatness.

3. Importance of BMI Calculation

Details: BMI is a simple screening tool for weight categories that may lead to health problems. For seniors, slightly higher BMI may be beneficial compared to younger adults.

4. Using the Calculator

Tips: Enter weight in kg and height in meters. All values must be valid (weight > 0, height > 0). For older adults, BMI interpretation may differ.
