You mean BMI: I believe you are talking about bmi ( body mass index). According to bmi calculator your current bmi is about 30.47 and you are overweight. Normal weight bmi should be below 25 . You can very easily find the bmi calculator on the internet. You just input your height and weight and it will do the calculation for you. There's also has bmi app you can download for your smartphone or ipad.
