Need help measuring your weight?

BMI (Body Mass Index) is the official unit of measurement for underweight, normal weight and obesity and it is aplied by WHO (World Health Organization).

BMI shows the ratio between your weight and your height. Despite the fact that it is not completely reliable, it gives a fairly good estimate of your current condition. Note that BMI doesn't take into account that muscle mass weighs more than body fat. BMI shouldn't be used by body builders, elite level sportsmen, children and persons under the age of 18.

To measure your own BMI, enter your height and weight data in the boxes below and click Show Information. If you would like to enter your data using the metric system, just click the Metric tab.
