BMI categories follow the Chinese adult standard
BMI is weight in kilograms divided by squared height in meters. Categories use Chinese adult thresholds of 18.5, 24 and 28 for ages 18 and over. It is a rough screening measure, not a diagnosis.
An example to check
Input and settings
Height 170 cm; weight 65 kg.Expected result
65 / (1.70 × 1.70) ≈ 22.5The result falls in 18.5 ≤ BMI < 24. The reference weight range uses BMI 18.5 through 23.9; it is a displayed interval, not a personal weight-loss target.
Scope and limitations
- Do not apply this classification to children, pregnancy or high-muscle individuals based solely on height and weight. Older adults need a suitable assessment.
- BMI does not measure fat distribution, nutritional status or disease. Consider waist circumference, medical history and professional assessment when concerned about health.
