A herbal extract ratio converter turns a label like 10:1 into something you can picture: how much dried plant went into the amount of extract in your capsule.

Enter the ratio and the amount, and choose which way you want to convert.

What 10:1 means

A ratio of 10:1 means about 10 parts of dried plant were used to make 1 part of extract. So 500 mg of extract stands for roughly 5,000 mg, or 5 g, of dried herb.

The bigger the first number, the more concentrated the extract.

Two quick examples

300 mg of a 4:1 extract equals about 1,200 mg of dried herb.

To match 1,000 mg of dried herb with a 5:1 extract, you need about 200 mg of extract.

What the ratio does not tell you

It says how much plant went in, not how much of any active compound came out. Two 10:1 extracts can differ a lot if the plant part, the solvent, or the method differs.

For the active compound itself, look for a standardization percentage and use the Extract Strength Calculator.

Tinctures use a different ratio

Liquid extracts often show ratios like 1:2 or 1:5. Those compare plant weight to liquid volume, so this converter does not apply to them.

Some labels also list an extract together with fillers or carriers. If the extract and the filler are listed separately, use the extract amount alone.

Put the result to use

Once you know the dried herb amount, you can compare it with what research used through Study Dose vs Product Dose. If an ingredient sits inside a blend with no amount, the Proprietary Blend Estimator shows its upper limit, and the Cost Per Dose Calculator compares what each dose costs.
