About BMI Calculator
Our BMI calculator is a professional health assessment tool designed for personal health management, medical professionals, and fitness enthusiasts. It provides accurate body mass index calculations to help you understand your weight status and develop appropriate health plans.
Formulas
BMI = weight (kg) / height² (m²)
BMI Prime = BMI / 25
BMI is only an estimate that cannot take body composition into account. Due to a wide variety of body types as well as distribution of muscle, bone mass, and fat, BMI should be considered along with other measurements rather than being used as the sole method for determining a person's healthy body weight.
