What Is a BMI Calculator?

A BMI Calculator is a simple tool that estimates your Body Mass Index (BMI) using your height and weight. BMI is commonly used as a general screening measure to classify weight relative to height.

The EasyTools365 BMI Calculator supports metric and imperial measurements, making it easy to calculate BMI online using the units you prefer.


How to Use the BMI Calculator

  1. Select metric or imperial units.
  2. Enter your height.
  3. Enter your weight.
  4. Click the calculate button.
  5. View your BMI result and category.

How Is BMI Calculated?

For metric measurements, BMI is calculated by dividing weight in kilograms by height in meters squared.

BMI = weight (kg) / height² (m²)

For imperial measurements, the calculation uses weight in pounds and height in inches with the appropriate conversion factor.


Understanding BMI Results

BMI categories provide a general way to interpret the calculated number. BMI is a screening measure and should not be considered a medical diagnosis.

  • Below 18.5: Underweight
  • 18.5–24.9: Normal weight
  • 25.0–29.9: Overweight
  • 30.0 or higher: Obesity

Individual health circumstances vary, so BMI should be considered alongside other relevant health information.
