Depends on the brand - but for Bakers 1 square = 1 ounce.
5oz = 142g
There is no square relevant to tablespoons.
Baking chocolate squares are about 1 ounce of chocolate (although some may be smaller 1/2 ounce squares). You can use a food scale to measure out the corresponding amount of chocolate chips - ie 4 ounces of chips for 4 squares. If you don't have a scale I've found that this usually works out to about 3/4 cup of chocolate chips.
4.5 oz
16 ounces
86 semi-sweet chocolate chips equals 3 squares of semi-sweet baking chocolate.
you will need 16 squares or 2 cups
6 ounces of chocolate chips = 1/3 cup = 1 baking chocolate square
If you mean 1 oz squares (ie Baker's), 12 ounces would equal one 12-ounce bag of chips, or about two cups. Nestle's is making baking squares that are only half an ounce, so 12 of those would be 6 ounces of chips, or about one cup.
12 ounces of Chocolate Chips equal 12 squares of baking chocolate.
24 is not Correct. Who ever that is just being Silly. Baker Squares are 1 oz each. and there is 16 oz in a pound(lb) So you would need 16 Squares of Bakers baking Chocolate to get a pound.\ And there is 32 in 2 pounds
One square of baking chocolate usually equals one ounce. Check the packaging to be sure, especially if the chocolate is not made in the USA. A recipe that asks for two squares of bakers chocolate generally means two ounces of chocolate. Remember that baking chocolate is most often unsweetened, so you should not substitute milk chocolate or semisweet because these chocolates already have sugar added.
