120lbs
5kg
About 80 pounds
125-135lbs
90 pounds
65-80 pounds
45-55 kilos

Go to this website and enter your height and weight. a healthy weight should be a BMI of 19-25
This average would be distorted, as there are so many overweight people, but the healthy weight for a girl of 5 foot would be between 90 to 110 pounds
