How to measure broccoli/vegetables properly?

So I have yet another stupid question. I'm sure I'm over thinking it but being as this could completely change how much I end up buying/making each week, I want to make sure I'm doing it right.

I would like to cook 2 days or so worth at a time that way it's easier to just pack for lunch each day.

The bulk broccoli I've bought shows the following:
1 cup (85g) = 30 calories, 1 protein, 0 fat, 4 carbs

I pretty much made all of one bag which should be 13 cups. I want to eat 1 cup with both my lunch and dinner each day. Should I just try to measure out 1 cup? Should I weigh it as I believe 85g would be 2.55oz? I'm thinking the raw weight/cooked weight are going to be entirely different and it would be heavier cooked, or would it be close? I understand it's only 30 calories but I'd rather figure it out and know so I can know how much to eat/make/buy.

Thanks.

Steamer bags??? If that's the case I think the nutrition label is for the cooked as there is no way of measuring it out until you steam the whole bag

Weigh it uncooked, get total weight and work out calories.

Once cooked, weigh it again and divide it into equal portions.

Divide the uncooked weight (not literally) into same amount of portions and you'll know calories.

So for eg, 1/13 (1 cup, you say you get 13cups total) of it uncooked is the same as 1/13 of overall cooked weight

Thats how i do it

Hope that made sense :s lol

I usually measure it by feet

I find weighing broccoli is easier. You can try the process yas360 outlined, but the caloric difference for the same weight of raw and cooked broccoli isn't significant.

The USDA National Nutrient Database for Standard Reference ([url]http://ndb.nal.usda.gov/[/url]) shows 100 grams of cooked broccoli (boiled, drained) has one extra calorie versus raw, and the same difference shows for 85 grams.
