------ Adult weight algorithm ------

Male: (height cm - 80) × 70% = standard weight
Female: (height cm - 70) × 60% = standard weight

Between plus or minus 10% of the standard weight of normal weight
Standard weight between plus or minus 10% to 20% of overweight or underweight
Standard weight than plus or minus 20% were obese or underweight

------ Children and adolescents weighing algorithm ------

Standard weight (kg) = Age x 2 + 8

Normal weight between plus or minus 20% of the standard weight
Standard weight between plus or minus 20% to 30% of mild overweight or underweight
Standard weight between plus or minus 30% to 50% as moderately overweight or underweight
More than plus or minus 50% of the standard weight for severely overweight or severely underweight

------ Infants weighing algorithm ------

1 to 6 months: birth weight (kg) + month old × 0.6 = standard weight (kg)
7 to 12 months: birth weight (kg) + month old × 0.5 = standard weight (kg)
Over 1 year old: Age × 2 + 8 = standard weight (kg)

Between plus or minus 10% of the standard weight of normal weight
20% more than the standard weight mild obesity ( mild excess nutrients )
More than 50% of the standard weight of severe obesity ( severe excess nutrients )
15% lower than the standard weight mild weight loss ( mild malnutrition )
Less than 25% of the standard weight severe emaciation ( severe malnutrition )

Body mass index (BMI)

BMI index (body mass index, English as a Body Mass Index, abbreviated BMI), is the weight in kilograms divided by height in meters squared that the number is a measure of body fat, thin degree as well as a common international standards are healthy . Mainly for statistical purposes, when we need to compare and analyze a person's weight to height of different people about the health impact, BMI value is a neutral and reliable indicators.

Body mass index (BMI) = weight (kg) ÷ height in meters squared (㎡)

Underweight: ＜18.5
Normal: 18.5 ~ 24.99
Overweight: 25 ~ 28
Obesity: 28 ~ 32
Very obese: ＞32

Experts pointed out that the ideal body mass index was 22.
