1. What is BMI?

Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is BMI = kg/m² where kg is a person's weight in kilograms and m² is their height in meters squared. 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 (kg)
• \( height \) — Height in meters (m)

Explanation: BMI compares your weight to your height to estimate body fat. It's calculated by dividing weight in kilograms by height in meters squared.

3. Importance of BMI Calculation

Details: BMI is a screening tool that may indicate whether a person is underweight, normal weight, overweight, or obese. Healthcare providers use BMI to help assess health risks associated with weight.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q4: What's a healthy BMI for adult females?
A: Generally 18.5-24.9, though individual health factors should be considered.

Q5: Should BMI be the only measure of health?
