It says on all the oats labels, 150 calories per 1/2 cup (dry), or 40 g (dry). So, I have been assuming all along this meant "measure out 1/2 cup dry oats before cooking, and you have 150 calories".

To make sure I checked the web for conversions from cups to grams. They all say 1/2 cup = 115 grams!! What the heck? Am I unknowingly consuming almost 3 times the calories??

Cups and grams are measurements of two different things--volume and weight. So you can't really say a cup equals a certain amount of grams, because it depends on the thing being measured. A cup of flour does not weigh the same thing as a cup of molasses, and I bet neither one of them weighs 115 grams. Point being, the only way you can be sure you're consuming 40g of oats is to get a scale and weigh out 40g of oats. If the Nutrition Facts on the package of oats says that also happens to be 1/2 cup volume-wise, take their word for it. They're the best source for a weight-volume conversion that you've got. And in general, 1/2 cup of dry uncooked oats is always, without fail, 150 KCal.

I concur dude. :tucool:

Thanks! I was pretty sure I wasnt eating a 700 calorie bowl of oats :lol:

Last poster is right. 1/2 cup OF WATER is about 115 grams because a cup of water is 250 ml, which is 125 ml when split in half (and a gram of water is one ml) so that's close to 115 grams. Your calculation with the oats was correct. Take what it says on the packet. 1/2 cup of dry oats is 150 CALORIES (or kcal if you want to get into it!) Whether you eat them raw or cook them so much that they take up five bowls, that 1/2 cup of dry oats is 150 calories.
