Why are baby weights always in pounds and ounces rather than kilos and grammes?
Answer Baby weights are given in pounds and ounces in the US because that is what parents will understand. In countries which use the metric system only, babies are weighed in kilos and grams, as you would expect. Sometimes grams are used in the US in special circumstances, such as for extremely premature babies whose weight needs to be tracked more precisely. For example, my triplets weighed 900g, 830g, and 810g at birth, which is more descriptive and shows the girls’ different weights better than 2 lb, 1 lb 13 oz, and 1 lb 13 oz. I can’t answer for practices overseas. If weights are given in pounds and ounces elsewhere, I was not aware of it, as all research and articles I have seen from other countries mentions the metric system instead.
