BMI is a screening tool for body fatness

A BMI Calculator is a simple yet powerful health tool that helps individuals assess whether their weight falls within a healthy range. BMI, or Body Mass Index, is a number calculated from a person's weight and height, providing a quick indication of body fat levels. It’s widely used by healthcare professionals and fitness experts to screen for weight categories that may lead to health problems. more calculator

Why Use a BMI Calculator?

Knowing your BMI can help you understand your current health status and make informed decisions about your lifestyle. The calculator uses a straightforward formula: BMI = weight (kg) / height² (m²) or the imperial equivalent, giving results that fall into categories:

  • Underweight: BMI less than 18.5
  • Normal weight: BMI between 18.5 and 24.9
  • Overweight: BMI between 25 and 29.9
  • Obese: BMI of 30 or more

These ranges help determine if you're at risk for health issues such as heart disease, diabetes, or high blood pressure.

Features of Our Calculator

  • Fast & Accurate: Just enter your height and weight, and get instant results.

Limitations

While BMI is a useful general indicator, it doesn’t consider muscle mass, bone density, age, sex, or overall body composition. For example, athletes may have a higher BMI due to muscle, not fat. Therefore, BMI should be used as a guideline, not a diagnosis.
