Can't get chocolate chips

I am trying to make fudge, but every recipe I find calls for chocolate chips which I can’t seem to locate here. I have bars of cooking chocolate. Can anyone advise weight ratio e.g. 1 cup chocolate chips = how many grams of cooking chocolate?

A cup is a measure of volume while grams is a measure of weight. It would be most accurate for you to simply shave or chop your bar chocolate and measures until you have a cup.

Thanks. I had thought of that, but was hoping for an easier way. :wink:
