1. What is Body Mass Index (BMI)?

Body Mass Index (BMI) is a simple calculation using a person's height and weight to assess body fat and categorize weight status. It is widely used as a screening tool to identify potential weight problems in adults.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

Where:

• \( weight \) — Body weight in kilograms (kg)
• \( height \) — Height in centimeters (cm)

Explanation: The formula converts height from centimeters to meters by dividing by 100, then calculates the square of height in meters, and finally divides weight by this squared height value.

3. Importance of BMI Calculation

Details: BMI provides a quick and easy method to screen for weight categories that may lead to health problems. It helps identify individuals who may be at risk for conditions like heart disease, high blood pressure, type 2 diabetes, and certain cancers.

4. Using the Calculator

Tips: Enter your weight in kilograms and height in centimeters. Ensure measurements are accurate for the most reliable results. The calculator will provide your BMI value along with the corresponding weight category.

5. Frequently Asked Questions (FAQ)

Q1: What are the BMI categories?
A: Underweight (BMI < 18.5), Normal weight (BMI 18.5-24.9), Overweight (BMI 25-29.9), Obesity (BMI ≥ 30).

Q2: Is BMI accurate for everyone?
A: BMI may not accurately reflect body fat in athletes (may overestimate due to muscle mass) or elderly (may underestimate due to muscle loss).

Q3: Can children use this calculator?
A: This calculator is designed for adults. Children and teens require age and sex-specific BMI percentiles.

Q4: What is a healthy BMI range?
A: For most adults, a BMI between 18.5 and 24.9 is considered healthy and associated with the lowest health risks.

Q5: Should BMI be the only measure of health?
A: No, BMI should be used as a screening tool along with other assessments like waist circumference, diet, physical activity, and family history.
