The quick answer
1 ounce of chocolate = 28 grams (about a 1×1 1/2-inch square, or 3 tablespoons of chips). So 4 oz = 113g, 6 oz = 170g, and 8 oz = 227g. Weight is more accurate than volume for chocolate because chopped, chips, and bar forms pack differently — when a recipe matters, weigh it.
Chocolate recipes love to mix units — ounces here, grams there, "1 cup of chips" somewhere else. Here’s a clean conversion chart plus the standard bar sizes so you can measure confidently every time.
Chocolate ounces-to-grams chart
| Ounces | Grams | Approx. cups (chips) |
|---|---|---|
| 1 oz | 28 g | 1/6 cup (3 tbsp) |
| 2 oz | 57 g | 1/3 cup |
| 4 oz | 113 g | 2/3 cup |
| 6 oz | 170 g | 1 cup |
| 8 oz | 227 g | 1 1/3 cups |
| 12 oz | 340 g | 2 cups |
| 16 oz (1 lb) | 454 g | 2 2/3 cups |
What does 1 ounce of chocolate look like?
One ounce is roughly a standard 1×1 1/2-inch square broken from a bar, a stack of about 3 "squares" of a snapping bar, or 3 level tablespoons of chocolate chips. If you don’t have a scale, that’s a close-enough visual for most recipes.
Why chips, chopped, and bars weigh differently by volume
A cup is a measure of space, not weight. Chocolate chips have air gaps between them, finely chopped chocolate packs denser, and a solid bar has none. That’s why "1 cup" can vary by 20–30 grams depending on form — and why professional recipes list grams. When precision matters (tempering, ganache ratios), always weigh.
Standard chocolate bar sizes
A typical full-size chocolate bar in the U.S. is about 1.55 oz (43g), while "king size" runs closer to 2.6–3.5 oz. Baking bars are usually sold in 4 oz (113g) blocks scored into ounce squares — convenient for the chart above.
Baking with real chocolate?
For melting and ganache, weigh good couverture rather than measuring chips by the cup. Our Gourmet Drinking Chocolate melts down cleanly for precise recipes.
