I strongly advise not to use the BMI (Body Mass Index), because it doesn't take gender nor individual differences into account. This calulator is only for informational purposes.
|Normal weight:||BMI 20 - 25|
|Grade I:||slightly overweight: BMI 22 - 30|
|Grade II:||overweight: BMI 30 - 40|
|Grade III:||heavily overweight|
