Chocolate chips

One US cup of chocolate chips weighs 168 grams. Going the other way, 100 grams is about 0.60 cups.

Also called semisweet chocolate chips, dark chocolate chips, milk chocolate chips, white chocolate chips, chocolate morsels, baking chips.

Sources agree within 1.2%, well inside any reasonable tolerance. USDA FDC 167976 (Candies, semisweet chocolate) publishes a cup at 168 g and specifies the portion as 1 cup chips from a 6 oz package. King Arthur's Ingredient Weight Chart lists standard chocolate chips at 170 g per cup.

Both figures rest on the industry labelling convention that a 12 oz bag of standard chocolate chips contains exactly 2 cups, which means 1 cup equals 6 oz equals approximately 168 to 170 grams. This is a packaging convention codified across Nestle Toll House, Ghirardelli, Guittard, Great Value, Hershey and generic supermarket brands, all of which state that their 12 oz bags contain 2 cups on the label. The convention is close to the true measured density but not identical to it.

USDA publishes different figures for different chip sizes on the same food record. Standard chips (the most common baking chip, roughly 60 chips per ounce): 168 g per cup. Mini chips: 173 g per cup, because smaller chips pack together more efficiently and leave less air space between them.

Large chips (Ghirardelli-style chunks, Nestle Toll House Premier Delights): 182 g per cup, because the larger pieces have less irregular geometry and pack denser again. King Arthur's chart lists mini chips at 177 g per cup, agreeing with USDA's mini figure within 2.3 percent. Chocolate chunks and roughly chopped chocolate weigh similarly to standard chips per cup at 170 g on the King Arthur chart.

The category assignment as sugar rather than as a distinct chocolate category is behavioural: chocolate chips are small discrete solid pieces that pack when scooped, and their measuring behaviour matches raisins and other small solid ingredients more than it matches liquids, milled powders or fats. Semisweet, dark, milk and white chocolate chips all publish at the same weight per cup because their bulk density is set by chip shape and packing efficiency, not by cocoa content. Cocoa solids and cocoa butter have similar densities in the 1.0 to 1.3 g/ml range once melted and solidified, and the differences between chocolate types (up to 90 percent cocoa in dark, down to 0 percent in white) do not measurably change chip cup weight.

Chopped chocolate from a bar rather than pre-formed chips can weigh slightly more per cup because the irregular pieces pack tighter, but King Arthur lists chopped chocolate at the same 170 g per cup as standard chips within their chart's precision. Cacao nibs, chocolate wafers, and couverture chocolate discs (Callebaut, Valrhona) have different geometry and densities, and are covered by separate entries when added. No standards body publishes a bulk density for chocolate chips.

FDA identity standards under 21 CFR 163.130 (sweet chocolate), 163.123 (milk chocolate) and 163.124 (white chocolate) specify composition requirements including minimum cocoa solids and milkfat but not physical density. Two sources agreeing tightly within category tolerance, so this entry publishes USDA's larger measure and is held at medium confidence until an independent third is found.
