Herb shrinkage varies by species and packing. Enter how many fresh units equal one dry unit; no herb-specific ratio is assumed.

Use Cases

Recipe Scaling

When a recipe calls for dry herbs but you only have fresh (or vice versa), use this converter to adjust the amount accurately.

Example: Recipe needs 1 tbsp dried basil; you have fresh basil with a 3:1 ratio. Enter 1 tbsp fresh, ratio 3, get 0.33 tbsp dry.

Meal Prep and Substitutions

Plan your herb usage when substituting fresh for dried in bulk cooking or preserving.

Example: You have 2 cups fresh parsley, ratio 3:1, convert to 0.67 cups dried.

Frequently Asked Questions

How does the fresh to dry herb converter work?
You enter the amount of fresh herb you have (in any unit) and the ratio of fresh units to dry units (e.g., 3:1). The calculator divides the fresh amount by the ratio to give you the equivalent dry amount in the same unit.
What is the typical fresh to dry ratio for herbs?
A common ratio is 3:1, meaning 3 parts fresh equals 1 part dry. However, ratios can vary by herb (e.g., 2:1 for some). Use the ratio that applies to your specific herb or recipe.
Can I use any unit for the fresh herb amount?
Yes, you can use any unit (e.g., tablespoons, cups, grams) as long as you use the same unit for the dry equivalent. The calculator works with any unit because it only divides the numbers.

Tips & Common Mistakes

Tips

  • Always use the same unit for fresh amount and the result – the converter does not change units.
  • Check the specific fresh-to-dry ratio for your herb; common ratios are 2:1, 3:1, or 4:1.
  • For leafy herbs like basil or mint, a 3:1 ratio is typical; for woody herbs like rosemary, 2:1 may be more accurate.
  • If you're unsure of the ratio, start with 3:1 and adjust to taste in your recipe.

Common Mistakes to Avoid

  • Using different units for fresh amount and ratio – the ratio must be unitless (e.g., 3:1) and the result is in the same unit as the fresh amount.
  • Forgetting to divide by the ratio – some users multiply, which gives a larger dry amount than needed.
  • Assuming all herbs have the same ratio – always verify the ratio for your specific herb.
