Let me try this one more time.

The number of yeast cells per gram is set as a universal value under 'options'.

The program does not know, ask, nor does it care how many grams are in a packet for purposes of calculating the weight of yeast cells needed. If you look at the profile description of a dry yeast, there is no input for number of grams per package.

It uses the set universal parameter of how many cells per gram to figure out how many grams of yeast are needed. From there is will calculate the weight of cells required, the weight of yeast cells in the package, and the number of packets needed as SEPARATE CALCULATIONS.

So, you can set the number of cells per package of dry yeast at 5, 55 billion, 200 billion, or 200,000,000 billion and it will give you the same calculated number of grams of yeast which you need for a given recipe. The program will take this same number of cells per gram as set in the universal settings under 'options' to calculate the weight of dry cells of the package based upon the number of cells you tell it are in the package. It will then tell you how many packages are needed to reach the needed cell count.
