1. What Is BMI (Body Mass Index)?
Body Mass Index (BMI) is a simple numerical value that compares your weight to your height. It’s commonly used to classify a person's body weight as:-
>Underweight
>Normal weight
>Overweight
>Obese
BMI provides a quick screening method to understand your overall health based on body fat level.
2. Why BMI Calculation Is Important?
Knowing your BMI helps you:-
Understand if your current weight is within a healthy range
Identify potential health risks (diabetes, heart disease, etc.)
Track your fitness journey or weight loss/gain goals
Consult your doctor with better self-awareness
3. How Our BMI Calculator Works ?
Our free BMI calculator uses a simple formula:
> BMI = weight (kg) ÷ height² (m²)
You just need to enter:-
Your weight in kilograms (kg)
Your height in centimeters (cm)
It instantly tells you your BMI and its category (underweight, healthy, etc.)
4. BMI Categories & What They Mean?
Knowing your category helps you make informed lifestyle changes.
5. Who Should Use a BMI Calculator?
Adults aged 18–65
Anyone starting a fitness or weight-loss journey
Health-conscious individuals
People tracking body goals over time
> Note: This tool is not ideal for children, athletes, or pregnant women.
6. Limitations of BMI.
While BMI is useful, it doesn’t account for:
Muscle mass vs fat
Bone density
Body shape or gender differences
So, BMI is just one health indicator — not a full diagnosis.
7. Frequently Asked Questions:-
Q1: What is a normal BMI?
A BMI between 18.5 and 24.9 is considered healthy for adults.
Q2: Is BMI reliable for athletes?
Not always. Muscular people may appear overweight on BMI charts even if they’re very fit.
Q3: Can BMI change with age?
Yes. As people age, muscle mass may decrease, and fat distribution changes — which can affect BMI readings.
Q4: How often should I check my BMI?
Every 1–3 months is ideal, especially if you're monitoring your fitness or health goals.
