Homepage/Fertility Calculator/BMI Calculator
Calculate BMI from height and weight, displaying weight categories based on Chinese adult standards or WHO/CDC guidelines. This is commonly used for preconception assessments and determining weight ranges before IVF treatment; results are for preliminary reference only.
Calculate the Body Mass Index (BMI) for adults and display the BMI classification based on the selected reference standard.
BMI = Weight (kg) ÷ Height (m)²; If height is entered in centimeters, BMI = Weight × 10000 ÷ Height (cm)².
| Standard | Category |
|---|---|
| Chinese Adults | <18.5 Underweight; 18.5–23.9 Normal; 24.0–27.9 Overweight; ≥28.0 Obese |
| WHO / CDC | <18.5 Underweight; 18.5–24.9 Normal; 25.0–29.9 Overweight; ≥30.0 Obese |
BMI value, classification under the selected standard, calculation formula, and standard description.
BMI is a screening indicator, not a direct measurement of body fat or fertility, and should not be used to estimate an individual’s IVF success rate. When addressing Chinese users, clearly specify the regional standards applied, and do not mix different standards.
