I think your numbers might be off. From https://www.livestrong.com/article/543411-how-much-curcumin-is-there-in-powdered-turmeric/ https://www.livestrong.com/article/543411-how-much-curcumin-... : "Turmeric contains approximately 2 percent curcumin by weight, so a tablespoon of turmeric, which weighs 6.8 grams, contains about 0.136 gram curcumin, or 136 milligrams."
