Body mass index (BMI) is a widely used international standard to measure obesity and health status.

160 height, body mass index = weight 90kg = weight kg/height m? =45/ 1.6/ 1.6≈ 17.57。

Body mass index < 18.5 is thin.

For girls whose height is 160cm, the standard weight is 160- 105=55kg. There are many formulas for calculating the standard weight of adults, and the formulas of different sexes are different. The formula for calculating the standard weight of women is height (cm)-70×60%.

Above 0/0% of standard weight/kloc-is overweight, above 20% is obese, below 10% is emaciation, and below 20% is emaciation. There is also a simple formula to calculate the standard weight of adults. The calculation method is standard weight (kg)= height (cm)- 105.
