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:

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

Explanation: BMI compares your weight to your height to estimate whether you're underweight, normal weight, overweight, or obese.

3. Importance of BMI Calculation

Details: BMI is widely used as a screening tool to identify possible weight problems in adults. While it doesn't measure body fat directly, research has shown that BMI correlates to direct measures of body fat.

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 most 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 genders, though women naturally have more body fat than men at the same BMI.

Q3: 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.

Q4: Are there limitations to BMI?
A: BMI doesn't account for muscle mass, bone density, or fat distribution. Athletes may have high BMI due to muscle rather than fat.

Q5: Is BMI accurate for pregnant women?
A: No, BMI calculations are not valid during pregnancy as weight gain is expected and necessary for fetal development.
