confused about onion calories

DKG28

Hey intelligent people,

I can't seem to find a reliable USDA entry on raw yellow onions. Everything from 100g = 100 calories to 100g = 40 calories comes up. I think the latter entry is correct, but I want to double check. I wouldn't care if I was using one slice on a sandwich, but I need to know for sauteeing a huge pile of them. Thanks!

Basically: 100g = 40kcal
