You're standing in the kitchen, flour up to your elbows, and the recipe suddenly demands 100 grams of butter. You look at your scale. The batteries are dead. Or maybe you never bought one because, honestly, who has the counter space? You reach for the silver spoons. But then you pause.
Does a tablespoon of lead weigh the same as a tablespoon of feathers? Obviously not.
The frustrating reality is that asking how many tablespoons is a 100 grams is a bit like asking how many minutes are in a mile. It depends entirely on how fast you’re moving—or in this case, what exactly you are scooping out of the jar. If you’re measuring water, the math is simple and elegant. If you’re measuring almond flour or packed brown sugar? It’s a mess.
Let's stop guessing.
The Golden Rule of Density
Density is the invisible hand that ruins birthday cakes.
Standard tablespoons measure volume. Grams measure mass. To bridge that gap, you need to know the specific weight of the substance. Pure water is the baseline for everything in the metric system. For water, 100 grams is exactly 6.67 tablespoons (assuming a standard 15ml tablespoon). But you aren't usually baking a cake made of just water.
Think about sugar. Granulated sugar is heavy. It sinks. A tablespoon of the white stuff weighs about 12.5 grams. So, for sugar, 100 grams is exactly 8 tablespoons. Easy, right? Now grab the flour. Flour is moody. It’s aerated. It’s fluffy. A tablespoon of "all-purpose" usually clocks in around 8 to 9 grams. That means 100 grams of flour could be anywhere from 11 to 12.5 tablespoons.
That’s a huge margin for error.

Butter, Oil, and the Liquid Exception
Liquids are generally more forgiving because they don't have "air pockets" like powders do. Most oils—olive, vegetable, canola—are slightly less dense than water. While water is 1:1 in the milliliter world, oil sits at about 0.9 grams per milliliter.
If you need 100 grams of olive oil, you’re looking at roughly 7.5 tablespoons.
Butter is the one that most people search for. In the United States, we have those handy markings on the wrapper. One stick of butter is 113 grams, which is 8 tablespoons. So, if you need 100 grams of butter, you’re looking at about 7 tablespoons plus a tiny bit more (roughly 7.06 tablespoons). Just cut a sliver off the end of a full stick, and you're basically there.
Honestly, with butter, being off by half a teaspoon rarely ruins a dish. It just makes it tastier.
Why 100 Grams of Flour Is a Trap
Flour is the enemy of the tablespoon.
If you dip your tablespoon directly into the bag and pack it down against the side, you might get 12 grams in that spoon. If you sift it first and gently spoon it into the measuring tool, you might get 7 grams.
When a recipe asks for 100 grams of flour, and you use the "dip and sweep" method with 8 tablespoons, you’ve actually only used about 70-80 grams. Your bread will be gummy. Your cookies will spread into flat, greasy puddles.

For 100 grams of all-purpose flour, you generally need 8 tablespoons plus 1 teaspoon if you are packing it tightly, or closer to 12 tablespoons if it’s sifted and light. This is why professional bakers like King Arthur Baking or Claire Saffitz treat scales like holy relics.
Honey, Syrups, and the Sticky Stuff
Sticky ingredients are the heaviest hitters in the pantry. Honey, molasses, and maple syrup are dense.
A single tablespoon of honey can weigh 21 grams. This means how many tablespoons is a 100 grams of honey? Just under 5. It’s only 4.75 tablespoons. If you used the "8 tablespoons" rule of thumb here, you would be adding nearly double the sugar the recipe intended. Your teeth would ache just looking at the result.
Common Pantry Conversions (The Quick List)
Forget the math for a second. Here is the "good enough for Sunday dinner" breakdown for 100 grams:
- Granulated Sugar: 8 tablespoons.
- Powdered Sugar (Sifted): 12.5 tablespoons.
- Brown Sugar (Packed): 7.5 tablespoons.
- Cocoa Powder: 13.5 tablespoons (it's incredibly light!).
- Milk or Cream: 6.7 tablespoons.
- Rice (Uncooked): 7 tablespoons.
- Salt (Fine): 5.5 tablespoons.
Notice the cocoa powder? It’s almost double the volume of sugar for the same weight. If you're making brownies and swap those volumes, you’ll end up with something that tastes like a chalkboard.
The International Spoon Crisis
Not all tablespoons are created equal.
If you are using a recipe from a vintage British cookbook, or perhaps an Australian one, the tablespoon might not be 15ml. In Australia, a "standard" tablespoon is often 20ml. In the UK, older recipes might use a "dessertspoon" which sits between a teaspoon and a tablespoon.

If you use an Australian tablespoon to measure your 100 grams of sugar, you only need 5 spoons, not 8.
Always check where your recipe originated. If it’s a modern digital recipe, it almost certainly assumes the 15ml standard, but "Grandma's Secret Recipe" is a wild card.
How to Measure Without a Scale (The Right Way)
If you absolutely refuse to buy a scale, you have to use the "spoon and level" method. Never use the measuring spoon as a shovel.
Use a separate, smaller spoon to fluff up your dry ingredient. Gently sprinkle it into the tablespoon until it’s overflowing. Take the back of a butter knife and scrape it across the top in one smooth motion. Do not tap the spoon. Do not press down. This gets you the closest to the "standard" weight that recipe developers use when they convert their grams to volume for the masses.
The Margin of Error
Most home cooking—soups, stews, roasts—has a huge margin of error. If you’re off by 10 grams of onions, nobody cares. Baking is different. Baking is chemistry.
If you are consistently finding that your bakes are too dry or too wet, it’s because your "tablespoon" isn't a fixed unit of mass. It’s a variable. Precision matters when you're dealing with leavening agents like baking soda or high-protein flours.
Practical Next Steps for Your Kitchen
Stop fighting the math. The most effective way to handle 100-gram measurements is to stop using spoons for weight-based recipes entirely. However, if you're in a pinch right now:
- Identify the Ingredient Type: Is it a heavy liquid (honey), a light powder (flour), or a standard liquid (water)?
- Use the 8-Spoon Baseline: For most granular solids like sugar, 8 tablespoons is your target for 100g.
- Adjust for Fluffiness: For flour or cocoa, increase your spoon count by 50% (up to 12 or 13 spoons).
- Use the "Knife Level": Always level off your spoons with a flat edge to ensure consistency.
- Buy a Digital Scale: You can find a decent one for under $15. It eliminates the need to ever search for these conversions again and saves you from washing ten different spoons.
The reality is that how many tablespoons is a 100 grams is a question with a dozen different answers. By sticking to the specific densities of your ingredients, you ensure that your 100 grams of flour doesn't turn into a 150-gram disaster. Consistency in the kitchen starts with understanding that volume is an estimate, but mass is the truth.
Actionable Insight: For your next bake, try the "Spoon and Level" method for flour and then weigh it afterward if you can borrow a scale. You will likely find you were over-measuring by at least 20%. Adjusting this one habit will immediately improve the texture of your cakes and breads.
