How many grams does an average newborn baby weigh?

The average weight of a newborn should be between 6.0 to 6.2 pounds. The 6.0 newborn weighs 2721.55 grams. The 6.2 newborn weighs 2812.27 grams.

Note: Infants typically lose 1 to 3 ounces within the first 24-58 hours. The average 6.0 to 6.2 pounds means they have enough weight to lose the 1-3 ounces without much problem and bounce back quickly. A newborn under 6 pounds has more risks but if close to 6 can add weight fairly easily. A newborn over 7 pounds might have issues with glucose.
