Synthetic thyroid hormones are expressed in metrics (micrograms or a
millionth of a gram). Natural or dessicated Thyroid Preparations are in
Grains. 1 Grain is equal to 60 mcgs.

To make the issue even confusing, Natural Thyroid Preparations express their
strengths based on standardized equivalence to the individual T4 or T3
component, not the actual content of these two. To do so, would be
impossible because individual thyroid gland used in the mixture has of
course different thyroid  content. So what is expressed is that if you take
a grain of Armour-- ithe effect is like taking an app. amount of thyroxine
or 1/4 of that as an equivalent of T3 alone.

You are not alone.. many of us are confused too!
