Fresh To Dry Herb Conversion
A precise tool.
What is the Fresh To Dry Herb Conversion & How does it work?
Fresh herbs contain a high percentage of water, typically ranging from 70% to 90% of their total weight. When a recipe calls for dried herbs, the moisture must be accounted for to maintain flavor balance.
The fresh‑to‑dry conversion factor expresses how many grams of fresh herb are needed to obtain one gram of dried herb. Common herbs such as basil, parsley, or thyme have ratios around 0.1 (i.e., 10 g fresh yields 1 g dried).
By entering the fresh weight and the appropriate ratio, this calculator instantly provides the equivalent dry weight, helping chefs and home cooks scale recipes accurately.
D = F times r
