does “ 12.8 lbs “ mean 12 lbs and 8oz, or does it actually mean 12.8 lbs, which would be around 12 lbs and 12oz?

Question

I came back from the pediatrician and she said my baby weighed “ 12.8 lbs “. Does that mean 12 lbs and 8oz, or does it actually mean 12.8 lbs, which would be around 12 lbs and 12oz?

I’m from a “kg” country so this is a bit confusing to me, and I’m not used to that dot in the middle. Basically, my question is – does my baby weight 5.8 kg or does he weight 5.6 kg?

Think about it this way – if 12.8 was supposed to be 12 lb 8 oz, then it would need to go all the way to .15.

Also, it would need to use a “leading 0” or else you wouldn’t know if 12.1 was 1 oz or 10.
