Recipes sometimes call for cups of chocolate chips when you're used to measuring in ounces. The good news is that the conversion is simple, and because the number of ounces -- and sometimes grams -- is listed on the chip bag, all you need to know is how to multiply. The quoted figure on the bag might not be exact, though; if you're looking for precision, use a digital scale.
Step 1: Check
Double-check how the recipe measures the chocolate chips and how the chip bag describes them -- usually in ounces or grams. Write down both figures.
Step 2: Measure
If your recipe needs precision or you don't know how many ounces of chips you have, use a digital scale. Place an empty plate on the scale, set the scale to zero and switch the reading to ounces. Pour the chocolate chips onto the scale and take note of the reading.
Step 3: Divide
Divide the number of ounces on the bag or your precise measurement reading by 6 to calculate how many cups of chips you have. For example, if you measured 6 ounces, you have 1 cup of chocolate chips.
Step 4: Repeat for Grams
If you want to convert grams of chips to cups of chips, repeat steps 1, 2 and 3, but remember to switch your scale to "grams" and use a different number to divide. In this case, use 160 -- about 160 grams of chocolate chips equals 1 cup. So, for example, if you have 150 grams of chocolate chips, you also have about nine-tenths of a cup.
To convert cups to grams, just multiply the number of cups by 160. For example, 2 cups of chocolate chips equals 320 grams.
