1. What is BMI?

BMI (Body Mass Index) is a measure of body fat based on height and weight that applies to adult men and women. It provides a simple numeric measure of a person's thickness or thinness.

2. How Does the Calculator Work?

The calculator uses the BMI formula:

\[ BMI = \frac{weight\ (kg)}{(height\ (ft) \times 0.3048)^2} \]

Where:

\( weight \) — Body weight in kilograms (kg)
\( height \) — Height in feet (ft)
\( 0.3048 \) — Conversion factor from feet to meters

Explanation: The formula converts height from feet to meters (by multiplying by 0.3048) and then calculates the ratio of weight to squared height.

3. Importance of BMI Calculation

Details: BMI is a simple screening tool that can indicate whether a person is underweight, normal weight, overweight, or obese. It helps assess health risks associated with body weight.

4. Using the Calculator

Tips: Enter weight in kilograms and height in feet. All values must be valid (weight > 0, height > 0). For accurate results, measure height without shoes and weight with minimal clothing.

5. Frequently Asked Questions (FAQ)

A: Underweight (<18.5), Normal (18.5-24.9), Overweight (25-29.9), Obese (≥30).

Q2: Is BMI accurate for everyone?
A: BMI may overestimate body fat in athletes and underestimate it in older people who have lost muscle mass.

Q3: Why convert height to meters?

Q4: Can children use this calculator?

Q5: What's a healthy BMI range?
A: For most adults, 18.5 to 24.9 is considered healthy, but individual factors should be considered.
