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
• \( height \) — Height in meters

Explanation: The formula divides your weight by the square of your height to give a number that helps categorize your weight status.

3. Importance of BMI Calculation

Details: BMI is a simple, inexpensive screening tool for weight categories that may lead to health problems. It helps identify potential weight problems in adults.

4. Using the Calculator

Tips: Enter your weight in kilograms and height in meters. For pounds and inches, convert first (1 kg = 2.2 lbs, 1 inch = 0.0254 meters).

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy BMI range?
A: For most adults, a healthy BMI is between 18.5 and 24.9. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is obese.

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

Q3: Should children use this calculator?
A: Children need BMI-for-age percentiles which account for growth patterns. This calculator is for adults only.

Q4: What are the limitations of BMI?
A: BMI doesn't distinguish between fat and muscle, doesn't account for fat distribution, and may not be accurate for certain ethnic groups.

Q5: What should I do if my BMI is high?
A: Consult your doctor who may suggest lifestyle changes, dietary adjustments, or further health assessments.
