Newborn baby weights can vary depending on a variety of factors, but the average weight of a newborn, male or female, is between 5 pounds 8 ounces and 8 pounds 13 ounces. However, baby girls are often smaller than boys at birth, but only slightly.
Ounces and pounds are the units used to measure newborns in the United States. In most other countries, the metric system is used, and birth weights are described in kilograms. There are 16 ounces in each pound and 1,000 grams in a kilogram. The average birth weight of a baby is 7 pounds and 8 ounces, or approximately 3.5 kilograms. As a reference, a developing fetus reaches a weight of 20 grams between the 12th and 13th week of gestation.
