Formula

287.8 g All-purpose Flour (100%)

0.518 g Active Dry Yeast (0.18%)

215.8 g Water (75%)

5.18 g Salt (1.8% )

1.5 g Dried herbs (0.52% )

I'm making this...but I don't get it?  .518 g of yeast?  

My scale doesn't have a "."

Or...what am I doing wrong?  518 sounds like a lot of yeast?

I know there probably is a simple answer and i'm going to feel really dumb asking! ;)

Thanks for the help!
