Cups to Grams Conversion for Baking (2026 Chart)

I was standing in the baking aisle doing math on my phone… and it still didn’t add up

I’m not even kidding — I was in the flour aisle, holding a 5 lb bag in one hand and my phone in the other, trying to figure out how many grams were in “2 cups” because the recipe I had was written like it came from a 1987 church cookbook. And the numbers were all over the place. One site said one cup of flour was 120 g, another said 130 g, and a third one said “it depends” (which is true, but also… not helpful when you’re trying to bake muffins before the kids wake up).

So I did what I always do when the real world is messy: I picked a standard, wrote it down, and kept going.

Because you don’t need perfection. You need cookies.

The 2026 cups-to-grams chart you’ll actually use

Here’s the thing: cups measure volume, grams measure weight, and those are not the same thing unless you’re measuring water (and even then, you can still make it weird if you try hard enough). For baking, you usually want grams because it’s consistent. But if your recipe is in cups, you need a conversion that’s at least in the ballpark of reality.

So below is a practical chart for common baking ingredients. These are typical “level cup” conversions — not packed, not heaping, not “I scooped straight out of the bag and called it a day.” If you do pack it, it’ll weigh more. If you sift it, it’ll weigh less. (Yeah, annoying.)

One cup of flour is about 120 grams. That’s it — one cup, one twenty-ish grams, assuming you’re not jamming the cup into the bag like you’re digging for treasure.

How to convert cups to grams without overthinking it

So the “math” part is simple. The annoying part is that the conversion factor changes by ingredient. Flour has air in it. Sugar settles. Cocoa powder is basically dust. And nuts are… nuts.

But if you’ve got a chart (like the one above) then you’re basically doing one multiplication and moving on with your life.

Here’s a worked example that’s real-life enough to hurt:

Example: Your recipe calls for 2.5 cups of all-purpose flour. You want grams.

• Flour conversion: 1 cup ≈ 120 g
• So: 2.5 × 120 = 300 g

And yes, you can do that in your head if you want: 2 cups is 240 g, half a cup is 60 g, total 300 g. Done. And it works!

But if you’re converting a whole recipe — flour, sugar, brown sugar, cocoa, chocolate chips — you’ll get sick of mental math fast. That’s where calculators are just… nice.

Use a quick converter for the general math:

If your recipe flips it the other way, you’ll want:

And when the recipe is in ounces because why not:

And if you’re stuck in “tablespoons and teaspoons” land (I’ve been there):

Honestly, the embedded calculator is what I’d use mid-bake because I’m not trying to touch my phone with butter hands and scroll through twelve ads for air fryers.

The stuff that quietly wrecks your conversions (and how to not get burned)

But here’s where people get tripped up, and I mean smart people too. You can do the multiplication perfectly and still end up with dry cake. Why? Because cups are squishy. Not literally, but you get me.

1) How you fill the cup changes the weight. If you scoop flour straight from the bag, you compress it. More flour fits in the cup. That can swing you from about 120 g up to 140 g for a “cup,” depending on how aggressive you are. And then you wonder why your pancake batter looks like drywall mud.

2) “Packed” is a real instruction. Brown sugar is the classic. If it says packed, pack it. If you don’t, you’re light on sugar and the texture changes. If you do pack it like you’re building a sandcastle, you’ll get closer to that ~220 g per cup number.

3) Different ingredients have different densities. That’s the whole game. A cup of chocolate chips is not a cup of flour is not a cup of honey. So if you’re ever tempted to use the water conversion (236 g per cup) for everything… don’t. That’s how you end up with 472 g of flour for 2 cups, and that’s a lot of flour!

4) Your “cup” might not be the same cup. Measuring cups are supposed to be standardized, but I’ve seen old plastic sets that are… let’s call them optimistic. If you’re serious about baking, a kitchen scale is the one tool that makes your life easier every single time.

So yeah, the chart gets you close, and close is usually fine. But if you’re baking something fussy (macarons, bread with hydration targets, anything where you text your friend “why is this dough screaming at me”), weigh it.

One scale. One bowl. No drama.
