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. It 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 — Measured in kilograms (kg)
• Height — Measured in meters (m)

Explanation: The formula divides your weight by the square of your height to give a standardized measure of body weight relative to height.

3. Importance of BMI Calculation

Details: BMI is a simple, inexpensive screening method for weight categories that may lead to health problems. It's used to identify possible weight problems in adults.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

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

Q2: Is BMI different for women and men?
A: The same BMI ranges apply to both women and men, but women tend to have more body fat than men at the same BMI.

Q3: What are the limitations of BMI?
A: BMI doesn't distinguish between muscle and fat, so athletes may have high BMI without excess fat. It also doesn't account for fat distribution.

Q4: How often should I check my BMI?
A: For most adults, checking every few months is sufficient unless you're actively trying to lose or gain weight.

Q5: Is BMI accurate for pregnant women?
A: No, BMI calculations during pregnancy are not accurate because of natural weight gain. Specialized assessments are needed.
