Walnut calories/ounces not adding up

[cobrien80]

So this might seem a dumb question but here goes...
I have seen on numerous nutrition sites that 7 whole walnuts, or 14 walnut halves = one ounce = 190 calories. This doesn't ever seem to match the weight listed when I buy nuts in bulk. I.E. I'll buy what bulk weight says is 1/2 lb of walnuts and I do NOT get 8 one ounce servings (or 112 walnut halves)--I get much less when I count them out.
Again, I know this might seem stupid but I'm trying to keep at maintenance calories and eat lots of healthy fats, so I eat a lot of these things. Now I'm worried that I've been doubling my portion size...Any thoughts? Thanks :)

IMO u r better off weighing them on a scale...size is too variable/inconsistant.

You need to invest in a scale if you want to eat 1 ounce worth of walnuts.

It was amazing to me that one slice of bread according to the package is 80 calories. But if you look at it closer it says 1 slice = 28g. I put a slice of bread on the scale and it weighed 40 grams, which is more like 114 calories! A different slice of bread weighed 23 grams!

A kitchen scale has really been an eye opener for me, if a serving size isn't listed in metric or imperial units, then it's hard to trust 1 or 2 of anything in that package is really the calories listed.
