Your age and sex is also needed to calculate weight if you are below 18. If you are above 18 then only height and sex are needed. If you are a man of over 18 years of age with a height of five feet and five inches then your weight should be 134-144 pounds or 60.78-65.32 Kg. If you are a girl of same height and age then your normal weight should be 57.61-61.23 Kg or 127-135 pounds.
