You’re standing in your kitchen, maybe mid-recipe, staring at a tiny pile of salt or a dusting of cinnamon. You need exactly one gram. You reach for a teaspoon. Then you stop. How many teaspoons are in 1 gram anyway?
It’s a question that sounds like it should have a straightforward, mathematical answer. You want a number. Maybe 0.2? Maybe 0.5? But honestly, if you’re looking for a single universal conversion factor, you’re going to ruin your dinner. Or your sourdough. Or your DIY face mask.
The reality is that grams measure mass. Teaspoons measure volume. They are fundamentally different things. It’s like asking how many minutes are in a mile—it depends entirely on how fast you’re moving. In the kitchen, it depends entirely on what you’re weighing.
The Physics of the Pinch
Let’s get the technical stuff out of the way first. A standard U.S. teaspoon is defined as exactly 4.92892 milliliters. For the sake of sanity, most of us just call it 5 mL.
If you’re measuring water, the math is beautiful. Water has a density of exactly 1 g/mL. So, 5 mL of water weighs 5 grams. This means that for water, there are 0.2 teaspoons in 1 gram.
But you aren't usually measuring a gram of water in a teaspoon. You’re measuring flour. Or sugar. Or heavy cream. Or lead shot? Probably not lead shot.
The problem is density. Some things are "fluffy." Others are "heavy." A teaspoon of lead weighs significantly more than a teaspoon of feathers, even though they take up the same amount of space in that little plastic spoon.
The Culprits: Why Your Measurement is Probably Off
When people ask how many teaspoons are in 1 gram, they are usually trying to bypass using a digital scale. I get it. Scales take up counter space. They need batteries.
But look at salt.

Table salt is dense. It’s composed of small, uniform crystals that pack together tightly. A gram of table salt is a very small amount, roughly one-sixth of a teaspoon. But take Kosher salt. The grains are huge, jagged, and flaky. They don't sit close together; they leave air gaps. A gram of Diamond Crystal Kosher salt takes up way more space than a gram of Morton’s Table Salt.
If you use a conversion chart meant for table salt while using Kosher salt, your food will be bland. If you do the opposite, you’ll be drinking a gallon of water just to survive the sodium hit.
Then there is the "sifted" factor. Flour is the ultimate villain here. If you scoop flour directly from the bag, you’re packing it down. You might fit 6 or 7 grams into a teaspoon. If you sift that flour first, making it airy and light, that same teaspoon might only hold 3 or 4 grams.
Breaking Down the Common Ingredients
If you absolutely must use a spoon to measure a gram, you need a cheat sheet that acknowledges these density differences. Keep in mind these are estimates.
White Sugar
Granulated sugar is fairly consistent. It’s heavy. For sugar, 1 gram is approximately 0.24 teaspoons. Basically, a quarter of a teaspoon.
All-Purpose Flour
This is where it gets messy. On average, 1 gram of flour is about 0.38 to 0.45 teaspoons. It’s almost half a teaspoon, but not quite. If you’re baking a cake where chemistry matters, this "almost" is the difference between a sponge and a brick.
Baking Powder and Soda
These are potent. You usually need exactly 1 gram for a specific lift. 1 gram of baking soda is about 0.21 teaspoons. Just a tiny bit over a fifth.
Dried Herbs
Ever tried to weigh dried oregano? It’s like weighing air. 1 gram of dried herbs can easily fill an entire teaspoon or more because they are so light and occupy so much volume.
The Metric vs. Imperial Nightmare
Just to make your life harder, not all teaspoons are created equal.
In the United States, we use the customary teaspoon (4.93 mL). In the UK, Canada, and Australia, they often use a metric teaspoon, which is exactly 5 mL. While the difference is small, it adds up if you’re scaling a recipe.
Even worse? The "spoon from the drawer."
If you are using a literal teaspoon—the one you use to stir your Earl Grey—stop right now. Those are not measuring devices. They are cutlery. One "teaspoon" from your silverware set might hold 3 mL, while another from a chunky modern set might hold 7 mL.
Why the "Gram to Teaspoon" Search is Skyrocketing
We are living in an era of globalized recipes. You find a brilliant creator on TikTok who lives in London. They list everything in grams because the metric system is logical and superior for cooking.
But you’re in a kitchen in Ohio, and you only have spoons.
You search for how many teaspoons are in 1 gram because you want to bridge that cultural gap. You want the precision of a European patisserie without the hassle of buying new equipment.
The honest truth? You can’t.
Precision and volume are enemies.
Does it Actually Matter?
Sometimes, no.
If you’re making a stew and it calls for a gram of black pepper, just toss a bit in. It doesn't matter. Your palate is the boss, not the math.

But if you are working with active ingredients—think yeast, or salt in bread, or stabilizers like Xanthan gum—1 gram is a massive deal. In those cases, the "volume guess" is a recipe for failure.
Take "The Bread Baker’s Apprentice" by Peter Reinhart. He emphasizes that professional results come from baker’s percentages, which are based entirely on weight. Why? Because a cup of flour can weigh anywhere from 120 to 160 grams depending on how you scoop it. That’s a 30% margin of error.
If you apply that same error margin to your "teaspoons in a gram" conversion, your results will be inconsistent at best.
Real-World Conversions for Quick Reference
Since I know you still want the numbers, here is a breakdown for 1 gram of the basics, assuming a standard 5 mL measuring teaspoon:
- Water: 0.2 tsp
- Whole Milk: 0.19 tsp (it's slightly denser than water)
- Vegetable Oil: 0.22 tsp (oil is lighter/less dense than water)
- Fine Sea Salt: 0.18 tsp
- Granulated Sugar: 0.24 tsp
- Confectioner's Sugar: 0.38 tsp (it's much fluffier)
- Ground Cinnamon: 0.45 tsp
The "Aha!" Moment: Using a Scale
If you find yourself searching for these conversions often, do yourself a favor. Buy a jewelry scale. Not a big kitchen scale—though those are great for flour—but a small, high-precision milligram scale.
They cost about $15. They fit in a drawer.
When you need 1 gram of a spice, you just put a little bowl on the scale, hit "tare," and shake the spice in until it says 1.00. No math. No guessing. No searching the internet for density tables of turmeric.
Actionable Advice for Your Kitchen
So, what should you do right now?
- Check the substance. If it’s a liquid, you can safely assume 1 gram is 1/5th of a teaspoon (0.2).
- The Quarter-Teaspoon Rule. For most heavy dry goods (salt, sugar, baking soda), 1 gram is roughly a level quarter-teaspoon. It’s not perfect, but it’s the closest "standard" spoon size we have.
- Level your spoons. Never use a "heaping" teaspoon unless the recipe says so. Use the back of a knife to scrape the excess off the top. This at least gives you a consistent volume to work with.
- Consider the Brand. If you’re using 1 gram of a specific supplement or powder, check the packaging. Often, they include a tiny "scoop" that is calibrated specifically for that powder’s density.
Calculating how many teaspoons are in 1 gram is ultimately a game of physics. While 0.2 teaspoons is the "textbook" answer for water, your actual kitchen reality will vary by 50% or more depending on what’s in the jar. Stop guessing, start weighing, or at the very least, stick to the quarter-teaspoon estimate for your heaviest powders.
