I guess I did not word my question correctly.
Let's say 1 cup of dry oats provides 54g of carbs. Once ground up, how can I figure out how many grams of carbs I'm getting? If I want to grind up a few cups and keep them readily available instead of grinding up 1 cup at a time every time I need them. How can I figure out how many grams of carbs I'm getting in 1 cup of ground up oats? Obviously there would be more oats in 1 cup if ground up vs 1 cup of oats in their normal form.
