Carrots, grated

One US cup of carrots, grated weighs between 99 and 130 grams, depending on how the cup is filled and which source measured it. That range is the answer; a single number would not be. Every figure behind it is below, with the method each source used.

Also called grated carrots, shredded carrots, carrots shredded, grated carrot, shredded carrot.

Grated carrots weigh 99-130 g/cup depending on grate coarseness and packing pressure. King Arthur's chart sits at the low end (99 g/cup, representing a coarse loose measurement), USDA and most aggregators cluster at the standard 110 g/cup, and firmly packed measurements can reach 130 g/cup.

Carrots are dense root vegetables (about 88% water, 12% cellulose and sugars), and grating them creates a mass of thin strips with substantial void space between the pieces. How much air ends up in a cup measurement depends on two independent factors that combine multiplicatively: the size of the grater holes, and how firmly the shreds get pressed into the cup.

King Arthur has this at 99 g/cup on their weight chart, and unlike many entries in this catalog, no correction is warranted here. KA's figure represents a defensible loose spoon-and-level measurement of coarsely grated carrot — it just happens to be at the low end of what home bakers actually produce when they follow a recipe. The USDA standard of 110 g/cup sits about 11% higher, reflecting a slightly more compact conventional loose measurement, and CupOrGram's firmly-packed 130 g/cup sits 31% above KA and represents what happens when a baker presses the shreds down with the back of a spoon.

The two independent variance factors matter differently in different recipes. For carrot cake, morning glory muffins, and quick breads, the recipe wants moisture as much as it wants fiber, so a firm pack that includes more carrot flesh per cup shifts the batter toward wetter and denser. Coarse-grated carrots also release water more slowly during baking than fine-grated, which affects how the batter behaves in the oven. For coleslaw, carrot fritters, and other savory applications, the moisture-vs-fiber tradeoff matters less and the coarse-vs-fine choice is driven by texture preference.

Pre-shredded bagged carrots (sold in grocery produce sections) run drier and coarser than freshly-grated whole carrots; they measure closer to 100-105 g/cup and behave differently in baking because they have already lost some surface moisture during packaging and refrigeration. Recipes tested with fresh grated should be weight-scaled if substituting bagged shreds.

Practical guidance: for baking recipes that specify grated carrots in cups without a gram weight, 110 g/cup is the most defensible middle-of-range assumption for standard loose measurement. If a recipe specifies 'packed' grated carrots, use 130 g/cup. If the recipe was tested against a specific brand or grate size, that gram figure is more reliable than any general conversion. For carrot cake specifically, a 10-15% variance in carrot amount affects moistness noticeably but is rarely catastrophic — carrot cake is a forgiving recipe, and the water content of the carrots themselves also varies by season and storage, which recipes accommodate by design.

Substitutions for grated carrots in baking: shredded zucchini works closely (see zucchini-shredded entry — that ingredient runs 121-150 g/cup with much more water content), producing a similar moist crumb but without carrot's color and mild sweetness. Grated apple substitutes 1:1 by volume in some quick breads but shifts moisture release timing during baking. Grated parsnip works 1:1 by weight in savory applications but is starchier and less sweet than carrot.
