You're standing in the kitchen, flour dusting your favorite apron, and the recipe calls for 170 gram in cups. It sounds simple enough. Just grab a measuring cup and scoop, right? Honestly, that’s exactly where most home bakers go wrong. Measuring dry ingredients by volume—using those plastic or metal cups—is arguably the most inconsistent way to cook.
Weight is absolute. Volume is a suggestion.
If you take a cup of flour and pack it down, you might get 160 grams. If you sift it first, you might only get 120 grams. That’s a massive margin of error when you're trying to hit that 170g sweet spot. Precision matters in chemistry, and baking is just delicious chemistry.
Converting 170 Gram in Cups for Common Ingredients
The most annoying part of converting 170 gram in cups is that every ingredient has a different density. You can't just use one magic number. A cup of lead weighs more than a cup of feathers, and a cup of honey weighs way more than a cup of cocoa powder.
Let's look at granulated sugar. It's heavy. It’s dense. For standard white sugar, 170 grams is roughly 0.85 cups. That’s just a hair over 3/4 of a cup. If you’re using a standard U.S. legal cup (240ml), you’re looking at about 13.5 tablespoons.
All-purpose flour is the troublemaker. Depending on your "scooping" technique, 170 grams of flour is usually about 1 1/3 cups. But wait. If you use the "dip and sweep" method—shoving the cup directly into the bag—you might actually be packing 200 grams into that same space. If you use the "spoon and level" method, where you gently fluff the flour into the cup, 170 grams fits much more reliably into that 1.33 cup range.
The Math of Different Flour Types
Not all flour is created equal. King Arthur Baking, one of the most respected authorities in the industry, notes that their all-purpose flour weighs 120 grams per cup. In that case, 170 gram in cups would be exactly 1.41 cups.
Cake flour is lighter. It's milled finer. You might need closer to 1.5 cups to reach 170 grams. Conversely, whole wheat flour is dense and thirsty. You’ll hit 170 grams much faster, likely around 1.25 cups.
Liquids are a Different Story
Water is the baseline. In the metric system, 1 gram of water equals 1 milliliter. This is the beauty of the system. Since a standard US cup is roughly 236.5 milliliters, 170 grams of water is almost exactly 0.72 cups.
Milk is slightly denser than water because of the fats and sugars, but for home baking, the difference is negligible. You can treat it the same as water.
Honey and molasses? Forget about it. They are incredibly heavy. 170 grams of honey is only about 1/2 cup. If you try to use 1 1/3 cups of honey because that's what you used for flour, your cake will be a sticky, burnt disaster.
Butter: The Stick Method
Butter is usually the easiest to convert because the packaging does the work for you. In the United States, a standard stick of butter is 113 grams. So, 170 grams of butter is exactly 1.5 sticks.
In terms of cups, 170 grams of butter is 3/4 cup.
Most people don't realize that European butter often has a higher fat content and less water than American butter. While the weight (170g) remains the same, the way it behaves in your dough might change slightly. Brands like Kerrygold are staples for a reason—the consistency is top-tier.
Why Scale Accuracy Trumps Volume Every Time
I used to hate scales. I thought they were for "serious" chefs or people who did way too much math in their spare time. Then I realized my cookies were different every single time I made them. Sometimes they were puffy; sometimes they were flat and greasy.
The culprit was the cup.
When you search for 170 gram in cups, you're looking for a shortcut. I get it. But if you're serious about your sourdough or your birthday cakes, buy a digital scale. They cost fifteen bucks.
Think about humidity. On a swampy day in Florida, your flour absorbs moisture from the air. It gets heavier. A "cup" of flour on a humid Tuesday weighs more than a "cup" of flour on a dry Friday. A scale doesn't care about the weather. 170 grams is 170 grams, period.

The Global "Cup" Confusion
Here is something weird: not all cups are the same size.
- US Legal Cup: 240ml (used for nutrition labeling).
- US Customary Cup: ~236.6ml (what’s actually in your kitchen drawer).
- Imperial Cup (UK): ~284ml (mostly obsolete but still in old books).
- Metric Cup (Australia, Canada): 250ml.
If you’re following a British recipe and use an American measuring cup to find 170 gram in cups, you’re already off by about 15%. This is why the internet is full of "this recipe didn't work" comments. It wasn't the recipe. It was the cup.
Measuring Semi-Solids: The Messy Part
How do you measure 170 grams of Greek yogurt or peanut butter in a cup? It’s a nightmare. You have to pack it down to get the air bubbles out, then scrape it out with a spatula, losing half a tablespoon in the process.
For 170 grams of yogurt, you’re looking at roughly 2/3 of a cup.
For peanut butter, it’s closer to 3/4 of a cup.
Honestly, just put the bowl on the scale, tare it to zero, and bloop the yogurt in until the screen says 170. It's faster. It's cleaner. You have fewer dishes to wash. Who doesn't want fewer dishes?
Common Ingredients at 170 Grams
| Ingredient | Cup Equivalent (Approximate) |
|---|---|
| White Sugar | 3/4 cup + 2 tbsp |
| Brown Sugar (Packed) | 3/4 cup + 1 tbsp |
| Cocoa Powder | 1 3/4 cups |
| Chocolate Chips | 1 cup |
| Rolled Oats | 1 3/4 cups |
| Almond Flour | 1 3/4 cups |
| Sour Cream | 3/4 cup |
Notice the cocoa powder. It is incredibly light. If you tried to use the "standard" 3/4 cup for cocoa powder, you'd be missing almost half the required amount. Your chocolate cake would just be... a beige cake.
Real-World Example: The Perfect Pizza Dough
I was helping a friend make a 70% hydration pizza dough last weekend. The recipe called for 170 grams of water. He used a measuring cup and eyeballed it. The dough was a liquid mess.
We weighed his "cup" of water. It was actually 195 grams because he filled it to the brim instead of the line. That 25-gram difference sounds small, but it ruined the structural integrity of the gluten. We restarted using the scale, hit exactly 170 grams, and the crust came out with those beautiful leopard spots you see in fancy Neapolitan pizzerias.
Precision is the difference between "edible" and "extraordinary."
How to Get the Best Results Without a Scale
Look, if you're stuck in a vacation rental and there's no scale in sight, you have to do what you have to do. To get 170 gram in cups as accurately as possible, follow these rules.
First, aerate your dry ingredients. Use a fork to fluff up the flour or sugar in the container before you measure.
Second, use the "spoon and level" method. Use a large spoon to gently move the ingredient into the measuring cup until it heaps over the top. Don't shake it. Don't tap it on the counter. Use the back of a knife to scrape the excess off.

Third, for liquids, get at eye level. Don't look down at the measuring cup from above. Parallax error is real. You'll think you hit the line, but you're actually five milliliters over.
Actionable Steps for Your Next Recipe
Stop guessing. If you want to master 170 gram in cups, your best bet is to move away from the conversion mindset entirely and embrace the weight.
- Check your cup size. Look at the bottom of your measuring cups. If they don't say 240ml or 236ml, you're flying blind.
- Use a spoon for flour. Never, ever scoop directly from the bag. You're compressing the flour and adding up to 30% more weight than you think.
- Tare is your best friend. Put your mixing bowl on a scale, hit the tare button, and pour your 170 grams directly in.
- Keep a cheat sheet. Tape a small chart of your most-used ingredients to the inside of a kitchen cabinet. It saves you from googling with floury hands.
- Adjust for altitude. If you're high up in the Rockies, your 170 grams of flour might need more liquid because things dry out faster up there.
Ultimately, 170 grams is a specific physical mass. A cup is a hollow container. The more you rely on the former, the better your bread, cookies, and cakes will be.
