BMI Calculator Instructions

It is a reference index for assessing the ratio of height to weight. It is calculated as: body weight (kg) divided by the height (m) squared (BMI = kg / m2)

The Body Mass Index, the body mass index, is a closely related indicator of total body fat, mainly reflecting systemic overweight and obesity. Because BMI calculates the proportion of body fat, it is more accurate to measure the risk of heart disease and high blood pressure due to overweight.

For example: a 52 kg person with a height of 155 cm, the BMI is:

52 (kg) / 1.552 (m 2 ) = 21.6

The normal weight range is BMI=18.5~24
