There are about 5.9 cups in a kilogram of dark chocolate. One cup of dark chocolate weighs about 170 g spooned and levelled, so 1,000 g divided by 170 g gives 5.9 cups — approximately, because a cup is a volume and this ingredient does not weigh the same in every cup. Chocolate is sold by the kilogram to serious bakers and by the bag to everyone else, and the cup question comes up constantly because recipes talk in cups while chocolate is sold in grams. A kilogram of dark chocolate is a generous quantity — dozens of batches of cookies — and the cup count is the same whether you are melting it, folding it into batter or scattering it over a cake, because the density does not change with the job.

That 5.9-cup figure is the one to remember, and it is worth knowing what sits behind it. Dark Chocolate is used for ganache, brownies, fondue and baking, and in all of those jobs the recipe usually talks in cups while the shop sells by the kilogram. Chopped dark chocolate bars, for melting or folding into batters. The source for the cup weight is King Arthur Baking, with high confidence in the figure, and the method is spooned and levelled — spoon the ingredient into the cup and level it off, rather than scooping from the bag, which packs it down and adds weight. If you scoop, the same cup can hold noticeably more, and your 5.9-cup kilogram quietly becomes fewer cups than you counted on.

The conversion table

All figures below are computed from the same cup weight — one cup of dark chocolate is 170 g spooned and levelled — so the table is internally consistent. Grams are rounded to the nearest gram and cups to one decimal place; both are approximate.

250 g (quarter kilogram) 1.5 cups 250 g
500 g (half kilogram) 2.9 cups 500 g

A kilogram is also 2.20462 pounds, and a pound of dark chocolate is about 2.7 cups (454 g divided by 170 g per cup), so the kilogram figure of 5.9 cups is a little more than twice the pound figure. A tablespoon of dark chocolate weighs about 10.6 g and a teaspoon about 3.5 g, which is useful when a recipe calls for a spoonful rather than a cupful — though for spoon measures the scale is still the safer tool when the amount is small and the recipe is sensitive.

Worked example 1: buying a kilogram bag

Suppose you buy a 1 kg bag of dark chocolate for a double batch of chocolate chip cookies. The bag holds about 5.9 cups, and if each batch needs 2 cups — 340 g — the bag covers about 2.9 batches. In practice you will lose a little to spillage and to the last spoonfuls that cling to the bag, so plan on 3 full batches and treat the remainder as a bonus. This is the calculation that tells you whether the bulk bag is actually a bargain: divide the price of the bag by 2.9 and you have the cost per batch, which you can compare honestly with the smaller bag on the shelf.

Worked example 2: a recipe written in cups

Now take the recipe the other way round. You are making a chocolate layer cake with ganache and the recipe calls for 3 cups of dark chocolate. That is 510 g, so if your scale reads in grams you can weigh it directly and skip the cup entirely. If you are doubling the recipe, you need 6 cups, which is 1020 g; tripled, it is 9 cups or 1530 g. And if you only have the kilogram bag and no smaller measure, remember that 3 cups is about 51.0 percent of the bag — a useful sense-check when you are pouring from a large bag into a bowl and wondering whether you have taken too much.

Worked example 3: using up a half kilogram

A half kilogram — 500 g — of dark chocolate is about 2.9 cups. If you are a month of weekend brownies, and each serving or batch takes 4 cups (680 g), a half-kilogram pack gives you about 0.7 of them. A quarter kilogram, 250 g, is about 1.5 cups, and 100 g — the smallest pack size you will commonly see — is about 0.6 cups. Working from the bag downwards like this stops the most common bulk-buy mistake: opening a kilogram bag for a recipe that needs a quarter of it, and then storing the rest badly because there was no plan for it.

Method and source

The cup weight used on this page is 170 g per cup, measured spooned and levelled, from King Arthur Baking. Confidence is rated high: the figure comes from a published ingredient weight chart and is widely used by bakers. The method matters as much as the number. Spooning and levelling means spooning the ingredient into the measuring cup until it is heaped, then sweeping a knife across the top; scooping the cup through the bag compresses the ingredient and can add 10 to 20 percent to the weight. For a poured ingredient the figure is for the ingredient poured into the cup without packing. Every cup result on this page is therefore labelled approximate, and the honest advice is to verify with a kitchen scale whenever the recipe matters — a scale that reads grams costs little and removes the whole problem.

Practical guidance

Keep chocolate cool, dry and away from strong smells; it absorbs odours readily and blooms — that white haze — when it is stored warm or damp. Bloomed chocolate is still fine for baking and melting, even if it looks less pretty. When a recipe calls for cups of chips, do not melt and measure: measure the chips as they are, level, and melt afterwards. A kitchen scale is the fastest way to divide a kilogram bag between batches without waste.

Storage for a kilogram of dark chocolate deserves a sentence of its own: Cool, dry place, up to 1 year. A kilogram is a lot to store badly, so decant it into a sealed container as soon as the bag is opened, label it with the date, and keep the container where you will actually see it — ingredients hidden at the back of a cupboard are the ones that go stale unnoticed. If you buy in bulk to save money, the saving only survives if the second half of the bag is as fresh as the first when you reach it.

The most common mistake with kilogram-to-cup conversions is treating the cup as if it were a weight. It is not: a cup of water weighs 237 g, a cup of flour weighs 120 g, and a cup of shredded coconut weighs 85 g, all in the same cup. The cup measures volume, the kilogram measures weight, and the ingredient's density is the only bridge between them. That is why this site gives a different cup figure for every ingredient, and why a conversion you memorised for one ingredient will be wrong for the next. Keep the scale on the bench, use the cup figures as a planning tool, and weigh the ingredient when the recipe's success depends on the amount.

Frequently asked questions

How many cups are in 1 kg of dark chocolate?

There are about 5.9 cups in a kilogram of dark chocolate. One cup weighs about 170 g spooned and levelled, so 1,000 g divided by 170 g gives 5.9 cups. The figure is approximate: how you fill the cup changes the weight, so verify with a kitchen scale when it matters.

How many grams is 1 cup of dark chocolate?

One cup of dark chocolate weighs about 170 g, measured spooned and levelled, according to King Arthur Baking (high confidence). A tablespoon is about 10.6 g and a teaspoon about 3.5 g.

How many cups are in 500 g of dark chocolate?

There are about 2.9 cups in 500 g of dark chocolate — half the kilogram figure, since 500 g is half a kilogram. A quarter kilogram (250 g) is about 1.5 cups, and 100 g is about 0.6 cups.

Do chocolate chips weigh the same per cup as chopped chocolate?

Roughly, but not exactly. The figure here — 170 g per cup — is for dark chocolate as the source measured it. Chips are uniform and leave small air gaps; chopped chocolate packs a little tighter or looser depending on the size of the pieces. The difference is small — a few grams per cup — so for most baking either figure works, but weigh it when the chocolate is the main ingredient, as in ganache.

How should I store a kilogram of dark chocolate?

Cool, dry place, up to 1 year. Keep the bulk of the bag sealed and decant a working amount into a smaller jar, so the main supply is opened as rarely as possible.

Is the cup figure exact, or should I weigh it?

It is approximate. The cup weight of 170 g is a published average for dark chocolate spooned and levelled, and real cups vary with brand, grind, humidity and how you fill the cup. For everyday cooking the cup figure is fine; for baking, for costing a recipe, or for any recipe where the amount is critical, weigh the ingredient on a kitchen scale and use the cup figure only to plan.
