Normally, the weight of a woman with a height of 181 cm is more appropriate at 66.6 kg, and the weight of a man with a height of 181 cm is more appropriate at 70.7 kg. According to the World Health Organization’s algorithm, the standard weight for girls is (height cm – 70) x 60%, and the standard weight for boys is (height cm – 80) x 70%. Therefore, it is more appropriate for a female with a height of 181cm to weigh 66.6kg and for a male with a height of 181cm to weigh 70.7kg. If there is a difference of 7-14 kg from the normal weight, it is called overweight or underweight.
