How to Calculate BMI
The standard BMI formula is: weight (kg) / [height (m)]². It is the global standard for checking health status.
This calculation determines if you are in a healthy weight range, overweight, or obese based on your height.
Knowing your number is step one. KiloTrack helps you change it by tracking nutrition and habits without requiring an account.

Is My BMI Accurate?
The Body Mass Index calculator estimates body fat but has limitations. It does not measure muscle mass directly.
Athletes may have a high BMI due to muscle, not fat. That's why KiloTrack focuses on tracking MACROS (Protein) and body composition, not just a simple number.
