First, let's cover the calculation:

- Divide your weight (in kilograms) by your height (in meters).
- Divide the answer by your height again to get your BMI.

So the body mass index formula is as follows:

`BMI = weight / height²`

A BMI of 25.0 or more is overweight, than the healthy range is 18.5 to 24.9. BMI applies to most adults 18-65 years.

There are five basic ranges within the BMI scale:

- Underweight = less than 18.5
- Normal weight = 18.5 - 24.9
- Overweight = 25 - 29.9
- Obesity = 30 - 35
- Severe obesity = 35 and more
