About This Calculator
The Fresh to Dry Herb Conversion Calculator helps home cooks and professional chefs convert between fresh herbs, dried herbs, and ground herbs with herb-specific precision. Whether your recipe calls for dried oregano but you only have fresh, or you need to substitute ground thyme for dried, this calculator provides accurate conversions based on established culinary ratios for 27 different herbs and aromatics.
The calculator uses a comprehensive conversion database where each herb has its own unique ratio derived from culinary standards. Dried herbs are generally three times more concentrated than fresh, but this varies — basil and parsley have a 2:1 ratio while oregano and thyme follow the standard 3:1 ratio. Ground herbs are even more concentrated than dried. The calculator handles all these variations automatically: simply select your herb, enter the amount in any one form, and the equivalent amounts in the other forms are computed instantly.

Frequently Asked Questions
How does the fresh to dry herb conversion work?
Select a herb from the dropdown menu, enter the amount of fresh, dried, or ground herb you have, and the calculator instantly converts it to the other forms using herb-specific ratios. For most herbs, three parts fresh equals one part dried, but each herb has its own precise conversion factor.
What is the general rule for converting fresh herbs to dried?
The standard rule of thumb is 3:1 — use three times more fresh herbs than dried. For example, if a recipe calls for 1 teaspoon of dried oregano, use 3 teaspoons of fresh oregano. However, some herbs like basil (2:1), parsley (2:1), and sage (2:1) have different ratios, which is why our calculator uses herb-specific conversion data.
Can I convert ground herbs back to fresh?
Yes, the calculator works both ways. Enter the amount of ground herb you have and it will calculate the equivalent fresh and dried amounts. Ground herbs are more concentrated than dried, so you typically need less ground herb to match the flavor intensity of fresh or dried herbs.
Is dried herb stronger than fresh?
Yes, dried herbs are significantly more concentrated and have a stronger flavor than fresh herbs because the water content has been removed, concentrating the essential oils. This is why you need to use less dried herb when substituting for fresh. Add dried herbs early in cooking and fresh herbs near the end for best results.
What herbs does this calculator support?
The calculator supports 27 herbs and aromatics including basil, bay leaf, chervil, chili pepper, chives, cilantro, cinnamon, cumin, dill, fennel fronds, garlic, ginger, lemon grass, lovage, marjoram, mint, onion, oregano, parsley, rosemary, sage, sorrel, star anise, tarragon, thyme, and vanilla.
How should I store dried herbs for maximum freshness?
Store dried herbs in airtight glass containers in a cool, dark, dry place away from direct sunlight and heat sources. Properly stored dried herbs can maintain their potency for two to three years. Avoid grinding herbs until just before cooking to preserve their aromatic oils and flavor.
Can I substitute ground herbs for dried in any recipe?
Ground herbs are more potent than dried herbs and have a different texture, so substitution works best in cooked dishes like sauces, stews, and soups where the fine texture blends in. For recipes where texture matters, such as dry rubs or garnishes, use dried herbs instead of ground for better visual appeal and texture.
When should I add fresh vs dried herbs during cooking?
Add dried herbs at the beginning of cooking so they have time to rehydrate and release their flavors into the dish. Add fresh herbs during the last 10 to 20 minutes of cooking or as a garnish, as they are delicate and can lose their flavor if cooked for too long. This timing applies to cuisines worldwide including Indian, American, and British cooking.
