BMI Calculator

What is a BMI Calculator?

A BMI Calculator is a simple tool that helps individuals calculate their Body Mass Index (BMI). BMI is a numerical value derived from your weight and height. It provides an easy and quick way to assess whether you are underweight, have a normal weight, are overweight, or fall into the obesity category.

How to Calculate BMI

The formula to calculate BMI is straightforward:

BMI = Weight (kg) / [Height (m)]²

For example, if you weigh 70 kg and are 1.75 meters tall, your BMI is:

BMI = 70 / (1.75 * 1.75) = 22.86

What Do BMI Numbers Mean?

• Underweight: BMI less than 18.5
• Normal weight: BMI between 18.5 and 24.9
• Overweight: BMI between 25 and 29.9
• Obesity: BMI 30 or higher

Why is BMI Important?

BMI is widely used because it provides a general idea of a person's body composition. It’s a quick and non-invasive way to identify potential health risks associated with being overweight or underweight.

Limitations of BMI

• Doesn’t Account for Muscle Mass: Athletes may have a high BMI but low body fat.
• Ignores Distribution of Fat: BMI doesn’t indicate where fat is stored.
• May Not Apply to All Populations: Factors like age, sex, and ethnicity can affect BMI interpretations.
