Recipes switch between a thumb of fresh ginger and a teaspoon of powder without saying how the water left. This converter uses culinary ratios: about five parts fresh ginger to one part dried, about four to one for turmeric root, about three to one for garlic, and about four or five to one for goji and white mulberry leaf. Cinnamon is different. A stick and the powder are both already dried bark, so the grams stay the same.
Enter a weight in grams and the direction. If you start from fresh turmeric and ask for dried powder, the page also divides by 2.8 grams so you can see a rough teaspoon count. That teaspoon is a kitchen average, not a curcumin assay. The curcumin tool on this site is the one that turns powder into a literature range.
Do not use the ratio to invent a supplement dose. Drying concentrates flavor and some compounds, and it does not turn a soup ingredient into the extract used in a clinical trial. Harvest moisture changes the real ratio. Weigh the ingredient if the dish is sensitive to it.
The tool divides or multiplies by a culinary ratio: ginger about 5 to 1, turmeric root about 4 to 1, dried-style goji and mulberry leaf about 4 or 5 to 1, garlic about 3 to 1. Cinnamon is the exception: a dried stick and ground cinnamon are the same dried bark, so the weight stays 1 to 1. One teaspoon of ground turmeric is treated as about 2.8 g when you want a spoon estimate.
These are kitchen estimates for recipes, not supplement doses. Water content varies by harvest. Goji is usually sold already dried; the fresh figure is only a water-loss estimate.
No. A recipe conversion is not a milligram dose of curcumin, gingerol, or any other compound. Use it to scale a soup or tea, then read the linked guide for what studies actually tested.
Ground cinnamon and a cinnamon stick are both dried bark. You are changing the form, not removing water from a fresh root. One gram of stick is about one gram of powder.
This page uses 2.8 grams per level teaspoon of powder, which is a common kitchen average. Scoops and brands differ, so weigh the powder if the recipe is fussy.
