So, here is everything you need to know about BMI: what it is, how it functions, why it is important and the way to use our BMI calculator properly.
What Is BMI?
BMI is an abbreviation that means Body Mass Index. It is just a number that allows you to realize whether you are of healthy weight regarding your height. BMI is usually used by doctors and fitness experts to examine the possibility of having health risks due to underweight or overweight.
Here’s the formula:
BMI = weight (kg) / [height (m)]²
It tells you if you are:
- Underweight
- Normal weight
- Overweight
- Obese
This is not a perfect measurement, but it’s a quick and useful guide.
Why You Should Know Your BMI
Knowing your BMI can help you:
- Track your fitness journey
- Spot early signs of health issues
- Set realistic weight goals
- Stay motivated
- Make smarter diet or workout choices
Whether you’re gaining muscle, losing fat, or just staying healthy: your BMI is a number worth knowing.
How Our Free BMI Calculator Works
We made this calculator super beginner-friendly. You just need to:

- Click the “Calculate BMI” button
That’s it. Your BMI will be shown instantly along with a health category:

Example: Real BMI Calculation
Let’s say your weight is 70 kg and height is 170 cm.

- Apply the formula: 70 / (1.7 * 1.7) = 24.2

When BMI Might Not Be Accurate
Although BMI is helpful, it’s not perfect. It doesn’t consider:

For example, a bodybuilder may have a high BMI but low fat. Still, BMI is a great starting point for most people.
