BMI Calculator – How to Check Your Body Mass Index

The BMI Calculator is a simple tool to help you understand whether your weight is appropriate for your height. Body Mass Index (BMI) is a widely used measure in healthcare and fitness to identify underweight, normal weight, overweight, or obesity categories.

What is BMI?

Body Mass Index (BMI) is calculated using your weight and height. The resulting number gives an estimate of your body fat and indicates if you are at a healthy weight. BMI is especially useful for adults, but variations exist for children and teenagers.

How BMI is Calculated

The formula is:

BMI = weight (kg) ÷ [height (m)]²

For example, a person weighing 70 kg and standing 1.75 m tall will have a BMI of:

70 ÷ (1.75 × 1.75) = 22.86

This BMI falls within the “normal weight” range.
