Cups to Grams Converter

Convert cups to grams by ingredient density for flour, sugar, butter, rice and more. Fast cups to grams chart for accurate baking. The cups to grams result updates as you type, works offline, and is built for real recipe work on a phone or laptop.

What this cups to grams tool is for

Use this when a recipe gives cups but you want scale-accurate grams. It is most useful for baking because flour, sugar, butter, honey, oats and cocoa all have different weights per cup.

Useful ways to use this calculator

Best use cases
  • Convert American baking recipes to scale weights.
  • Compare flour brands without guessing cup packing.
  • Prepare repeatable bread, cake, cookie and pastry batches.
  • Convert pantry ingredients before meal prep.
Common mistakes to avoid
  • Do not assume one cup always weighs 240 g; only water is close.
  • Do not scoop flour hard into the cup unless the recipe expects dip-and-sweep.
  • Do not ignore ingredient choice; powdered sugar and granulated sugar differ a lot.
How to read the result

The gram result is the target scale weight for the selected ingredient and cup size. For flour, the fill-method setting intentionally changes the result because packed flour can weigh much more than spooned flour.

Formula for cups to grams

grams = cups x ingredient density in g per cup

Frequently Asked Questions

How many grams in 1 cup of breadcrumbs?

For dry, plain breadcrumbs, 1 US cup is about 108 grams. I always tell students to treat this as a working kitchen estimate, because crumb size changes the weight. Fine dry crumbs pack more tightly than fresh, fluffy crumbs. For breading, a few grams will not harm the dish, but for stuffing, meatballs, or costing, weigh the breadcrumbs on a digital scale and note the brand or texture used.

Why does 1 cup of flour weigh less than 1 cup of sugar?

Flour weighs less than sugar because the particles are lighter and trap more air between them. A cup measures space, not mass. Granulated sugar packs closely, so 1 cup is about 198 grams. All-purpose flour is powdery and airy, so 1 cup is about 120 grams. This is why professional kitchens prefer grams for baking. Weight removes guesswork and gives the same result every time.

How many grams in half a cup of flour?

Half a cup of all-purpose flour is about 60 grams when measured from the usual 120 grams per US cup. If your recipe says spoon-and-level, gently spoon flour into the cup and level it; do not press it down. Scooping straight from the bag can make the cup heavier. For cakes, bread, and sauces, weighing 60 grams is the cleanest and most repeatable method.

How many grams in 1 cup of yogurt?

One US cup of plain yogurt is about 227 grams. Greek yogurt, thick curd, and homemade yogurt can vary slightly because they contain different amounts of water and solids. In most recipes, 225 to 240 grams will work well. For marinades, smoothies, and batters, this small difference is usually fine. For nutrition labels, costing, or consistent hotel production, weigh the yogurt instead of relying only on cups.

How many grams in 1 cup of oats?

One US cup of old-fashioned or quick oats is usually about 89 to 90 grams. Some rolled oats are heavier, especially if the flakes are thicker or packed more tightly. That is why you may see 100 to 113 grams in some charts. For porridge, a small variation is acceptable. For cookies, granola bars, and nutrition costing, weigh the oats so the texture stays consistent.

How many grams in a cup of cocoa powder?

One US cup of unsweetened cocoa powder is about 84 grams. Cocoa is light, dry, and easily compacted, so the number changes if you press it into the cup. For best results, fluff the cocoa, spoon it into the cup, and level it. In cakes, brownies, and chocolate sauces, weighing is better because too much cocoa can make the product dry, bitter, or heavy.

How many grams in 1 cup of milk?

One US cup of fresh milk is about 227 grams on many baking charts, and about 237 milliliters by US volume. In everyday cooking, you can think of 1 cup milk as roughly 230 to 240 grams. The fat level changes the weight only a little. For beverages and sauces, measuring by cup is fine. For bakery formulas, weigh the milk for better consistency.

How many grams in a cup of chocolate chips?

One US cup of regular chocolate chips is about 170 grams. Mini chips can be a little heavier because they settle into the cup more tightly, while large chunks may be slightly lighter. For cookies, muffins, and brownies, 165 to 175 grams is a practical range. If you are costing a recipe or scaling for a hotel buffet, use the same chip size and weigh it.

How many grams in 1 cup of almond flour?

One US cup of almond flour is about 96 grams. Almond meal may weigh differently because it can be coarser and may include skins. Always avoid packing almond flour into the cup, because it compresses easily and can make cakes dense or oily. For macarons, gluten-free cakes, and keto baking, weighing is especially important. A small change in almond flour can noticeably change texture and moisture.
