To calculate your BMI, divide your weight in kilograms by your height in metres squared.
As this is a fairly complex formula, we provide the ObesiStop® BMI calculator to help you calculate your BMI.
Simply enter your data and click on the indicator button.
- 18.5 and 24.9 are considered normal
- 25 to 29.9 is considered overweight; and
- 30 and above is considered obese.
People with BMIs above 40 are considered morbidly obese. People with BMIs between 19 and 22 live longest, and death rates are noticeably higher for people with BMIs of 25 and above.
