The standard weight for a height of 1 meter 72 should be 67 kilograms, and a normal weight more or less than 10% of the standard weight is the normal range. Adult standard weight is calculated according to height, but there are many formulas for calculating adult standard weight, a simpler formula can be based on the standard weight in kilograms is equal to the number of centimeters of height minus 105, for example, a height of 1 meter 72, the standard body weight circumference of 1 meter 72 minus 105 for 67 kilograms. Standard weight plus or minus 10% for normal weight. More than 10% of standard body weight is overweight, more than 20% is obese, less than 10% of standard body weight is thin, less than 20% is emaciated. But it is worth noting that this algorithm is suitable for adults, for children, the elderly or too short people do not apply.
