Approximately one teaspoon of dried rosemary equals one tablespoon of fresh. (Approx. 1 tsp dry = 1 Tbsp fresh)
One small sprig of rosemary converts to 1/2 a teaspoon of dried rosemary.
About 2 to 3 tablespoons.
The weight of one sprig of rosemary can vary depending on its size and moisture content, but on average, a single sprig typically weighs between 0.1 to 0.5 grams. Fresh rosemary is lighter than dried rosemary, which has a denser concentration of flavor. For cooking purposes, recipes usually call for a few sprigs rather than measuring by weight.
When using dry herbs versus fresh herbs, a good rule of thumb is to use 1 portion of dry herbs for every 3 portions of fresh herbs. So, one tsp of dried tarragon would be the equivalent to 3 tsps. of fresh tarragon.
With thyme one fresh sprig equals one-half teaspoon of dried thyme. In general, use two to three times the amount of fresh thyme as dried. When adding to soups and stews, crush the leaves between your hands before stirring it in your recipe.
The amount of dill in a sprig can vary, but a general estimate is that one sprig of fresh dill typically equals about 1 teaspoon of chopped dill. If using dried dill, one sprig would equate to about 1/4 to 1/2 teaspoon, as dried herbs are more concentrated in flavor. Always adjust according to personal taste and the specific recipe.
As much as you want, - a "large" sprig could be any size, you are seeing it, not us.
You'll have to explain to us how you define the volume of a "sprig"
1 4" sprig yields approximately 1 Tablespoon of fresh oregano. 1 Tablespoon of fresh oregano is equivalent to 1 teaspoon of dried. Therefore, 1 sprig is approximately equal to 1 teaspoon dried, so 2 sprigs = approximately 2 teaspoons of dried oregano. :)
About 3 gm.
