Generally speaking, the standard weight of girls can be "height (cm)- 100". Girls with a height of 170cm have a standard weight of about 70kg, which belongs to the normal range. If you have to get to the bottom of it, you can refer to the following situations:

First, the height-to-weight ratio of girls will vary with age. Girls in different parts of the north and south have different weight standards.

1, the ideal weight of northerners = [height (cm)- 150] × 0.6+50kg,

The weight of a girl whose height 170cm is (170-150) × 0.6+50 = 62kg.

2. The ideal weight of southerners = [height (cm)- 150] × 0.6+48kg,

The weight of a girl whose height 170cm is (170-150) × 0.6+45 = 60kg.

Second, the formula commonly used in the world to calculate people's weight and the calculation of body proportion (more suitable for orientals)

Reference weight (female) = (height cm-100) x 0.9 (kg)-2.5 (kg)-60.5kg.

Normal weight: standard weight+-(how much) 10%-54.45 ~ 66.55kg.

Overweight: 10% is greater than the standard weight, and 20% is less than the standard weight -66.55 ~ 72.6kg.

Light and fat: 20% larger than the standard weight, 30%-72.6kg ~ 78.65kg smaller than the standard weight.

Moderate obesity: 30% larger than the standard weight and 50%-78.65 ~ 90.75kg smaller than the standard weight.

Weight and fatness: more than 50% of the standard weight-> 90.75 kg.
