The only butter I can find is salted.  Now what?  I've got a scales and now to figure.  I've seen some recipes that one "stick" of butter is 1/2 cup and that sometimes 1/4 teaspoon salt can be eliminated if salted butter is used.  I'm getting nervous...I would really appreciate some help. 

Q:  What is 1/2 cup of Butter in grams?  (Directly off the package, please)

Q:  And how many grams of salt are mentioned on the package for the test amount?  (usually 100g)

I thought I had a kilo of rye with me also but alas, I'm headed for withdrawal.  My baking world is stalling....help...
