How much is 1 tablespoon of dried herbs in grams?

It depends on the herb, as they are all different weight. Just as one pound of grapes will be larger than one pound of Apples. I also wish herbs were sold in measurements instead of weight due to the larg variety. You never know what you will get until you get it. My best advice, so far, is to buy the smaller weight, and buy more later if needed. Hopefully will have a better answer for you later... I'm researching the same thing.
