What is BMI Calculator?

BMI stands for Body Mass Index. It’s a number that tells if your weight is right for your height. This calculator takes your height and weight. Then it gives a number. That number falls into a category. It could be underweight, normal, overweight, or obese. The BMI calculator gives you a quick view of your body health.

Why I Used the BMI Calculator Tool

I wanted to lose some weight. But I did not know if I was in a safe range or not. I saw many apps, but most of them asked for signup. I found this free online BMI calculator. It was simple. I only had to enter my height and weight. Then it showed me my BMI. It said I was in the overweight range. That helped me to take it seriously. I started tracking my food and daily walks. In a few weeks, I saw improvement. That’s why this tool worked great for me.

How This Tool Works

The BMI calculator asks for two things. Your height and your weight. Once you enter these, it calculates a number. That number is your BMI. It checks if your body weight is suitable for your height.

Calculation Theory and Logic

The formula is simple. Here is how it works:

• BMI = weight (kg) ÷ height (m)²
• Example: If you weigh 70 kg and your height is 1.75 m
• BMI = 70 ÷ (1.75 × 1.75) = 22.86
• This BMI is in the “Normal” range

If you use pounds and inches, the formula changes a bit:

• BMI = (weight in lbs ÷ height in inches²) × 703

This is the same logic used in hospitals and fitness centers.

My Personal Experience

When I first used this tool, I was a bit unsure. But once I entered my numbers, the result came in a second. It showed a number along with the category. I realized I was on the edge of normal and overweight. That hit me. I started eating better. I reduced sugar. I walked every morning. In a month, I checked again. My BMI had dropped. That small number gave me a push to change. I still check my BMI every two weeks. It keeps me on track.
