1. What is BMI?

Body Mass Index (BMI) 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, allowing health professionals to discuss weight problems more objectively with their patients.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

Where:

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

Explanation: The formula calculates body mass index by dividing weight in kilograms by the square of height in meters.

3. Importance of BMI Calculation

Details: BMI is a simple, inexpensive, and noninvasive method to screen for weight categories that may lead to health problems. It's widely used by healthcare professionals to identify potential weight problems in adults.

4. Using the Calculator

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