Grams to Teaspoons Converter
3 grams of table salt is half a teaspoon, but 3 grams of flour is more than a full teaspoon. This grams to teaspoons converter handles the small measurements where precision matters most, salt, sugar, baking powder, spices, using each ingredient's real density instead of a single average rate. Enter the amount, pick the ingredient, and convert in either direction. Grams and teaspoons measure two different things. A gram is a unit of weight, while a teaspoon is a fixed unit of volume, about 4.93 ml in the US system. What fills that volume determines how much it weighs, which is why a teaspoon of honey weighs almost three times as much as a teaspoon of cocoa powder. Recipes written by weight are more reliable for exactly this reason, and this converter exists so home cooks can move between the two scales without leaning on a blanket 5-grams-per-teaspoon rule that really only holds for water. The tool covers eleven common baking and cooking ingredients, from all-purpose flour and granulated sugar to butter, honey, and baking powder, each with its own grams-per-teaspoon constant. Flip the direction toggle to go from teaspoons back to grams when a recipe lists a spoon measurement but your kitchen scale reads only in grams.
Quick answer
A US teaspoon is 1/48 of a cup, about 4.9 ml, and its weight in grams depends on what fills it.

What this tells you
- •A US teaspoon is 1/48 of a cup, about 4.9 ml, and its weight in grams depends on what fills it.
- •A teaspoon of table salt weighs 6 g, sugar 4.17 g, and flour only 2.6 g, more than double the range across common baking ingredients.
- •Grams to teaspoons: divide grams by the ingredient's grams-per-teaspoon. Teaspoons to grams: multiply teaspoons by that same constant.
- •Small-quantity ingredients like salt, baking powder, and yeast are where volume-to-weight mistakes hurt recipes most, since a small error is a large share of the total amount.
- •Dense, wet ingredients like honey and butter pack more weight per teaspoon than dry, powdery ones like cocoa powder or powdered sugar.
- •US and metric teaspoons differ by about 1.4 percent, 4.93 ml versus 5 ml, a gap no home recipe will ever notice.
- •Weighing instead of scooping matters most for flour, since how tightly it's packed into a spoon or cup can swing the actual gram amount noticeably.
How to Use
- 1Pick the ingredient you are measuring from the dropdown. Each one carries its own grams-per-teaspoon constant, so 5 grams converts to a different teaspoon amount for sugar than for flour.
- 2Enter the amount in grams or teaspoons, whichever your recipe or your kitchen scale gives you.
- 3Choose the direction of conversion, grams to teaspoons or teaspoons to grams.
- 4Read the result, with the density constant shown so you can verify the math or reuse it for a different quantity of the same ingredient.
- 5For an ingredient not on the list, check the reference table for a close match, such as using granulated sugar's rate as a stand-in for another fine, dry, granular ingredient.
How It Works
Formula
teaspoons = grams / grams per teaspoon (or grams = teaspoons x grams per teaspoon)Each ingredient has a weight per level US teaspoon, since a teaspoon is a fixed volume, 1/48 of a cup, about 4.93 ml, but different ingredients pack different amounts of mass into that same space. Table salt runs 6 g per teaspoon, so 3 g of salt is 3 / 6 = 0.5 teaspoons. Flour is much lighter at 2.6 g per teaspoon, so the same 3 grams fills 1.15 spoons, more than double the volume for the same weight. Converting the other direction just reverses the operation, teaspoons multiplied by the grams-per-teaspoon constant gives grams, so 2 teaspoons of baking powder at 4.8 g each comes out to 9.6 g. The constants used here are each ingredient's weight per cup divided by 48, matching how standard US recipe references measure density.

Worked Examples
3 grams of salt
Salt weighs 6 g per level teaspoon, so 3 g is exactly half a spoon. This is the classic case where eyeballing 3 grams as about a teaspoon would double the actual sodium in a recipe.
5 grams of sugar
Sugar runs 4.17 g per teaspoon, so 5 g works out to 1.199 teaspoons, just short of an extra quarter spoon past level. Rounding that to about 1.2 teaspoons is close enough for most baking, but a scale will read the precise figure.
2 teaspoons of baking powder to grams
Baking powder weighs about 4.8 g per level teaspoon, so 2 teaspoons is 9.6 g. This direction matters when a recipe lists a spoon measurement but the only tool on hand is a gram scale.
3 grams of flour
Flour is one of the lightest ingredients on this list at 2.6 g per teaspoon, so the same 3 grams that made half a teaspoon of salt fills 1.15 teaspoons of flour. A gram-for-gram assumption between ingredients falls apart fast for exactly this reason.
10 grams of honey to teaspoons
Honey is the densest ingredient in this list at 7.08 g per teaspoon, so 10 g barely clears 1.4 teaspoons. Its stickiness also makes a level teaspoon hard to judge by eye, another reason a scale reading is more dependable.
1 teaspoon of table salt to grams
A single level teaspoon of fine table salt weighs 6 g, the reference weight this converter uses for every gram-to-teaspoon salt conversion. Coarse kosher salt weighs roughly half that per spoon, so swapping salt types without adjusting the amount changes the sodium significantly.
Grams per Teaspoon by Ingredient
How much one level US teaspoon of each ingredient weighs.
| Ingredient | Grams per tsp |
|---|---|
| All-purpose flour | 2.6 |
| Granulated sugar | 4.17 |
| Powdered sugar | 2.5 |
| Table salt | 6 |
| Baking powder | 4.8 |
| Butter | 4.73 |
| Water | 4.93 |
| Honey | 7.08 |
| Cocoa powder | 2.08 |
Why Weight Beats Volume for Small Kitchen Amounts
Bakeries and professional kitchens weigh ingredients instead of measuring by volume for one main reason: grams are consistent and teaspoons are not. A cup of flour can weigh anywhere from about 120 to 150 grams depending on whether it is sifted, spooned, or scooped straight from the bag and packed down. A gram scale removes that variability entirely, which matters even more at the teaspoon scale, where a small measuring error is a much larger share of the total amount than the same error would be in a full cup.
This is especially true for ingredients that do heavy chemical work in small doses. Salt controls flavor balance and, in bread dough, controls fermentation speed. Baking powder and baking soda control rise. Yeast controls both flavor and rise timing. A teaspoon that ends up slightly heaping or slightly shy of level can shift these results more than the same percentage error would in a cup of flour, simply because the total quantity is already so small. Converting to grams and weighing on a scale accurate to at least 1 gram removes most of that guesswork.
Common mistakes
- Assuming 1 gram equals 1 teaspoon. A teaspoon of salt is 6 g and a teaspoon of cocoa powder is barely 2 g. There is no universal rate.
- Heaping the spoon. All these weights are for level teaspoons, and a heap can double the dose, which ruins salt and baking powder amounts.
- Swapping salt types. A teaspoon of fine table salt is 6 g, but coarse kosher salt is only about 3 g per spoon, half the sodium per scoop.
- Using a liquid measuring cup for small amounts. A one or two teaspoon quantity is hard to read accurately in a cup meant for quarter-cup increments, so use a proper measuring spoon or a gram scale instead.
- Rounding mid-recipe. Rounding 3 g of yeast to about a teaspoon seems harmless, but that kind of loose rounding compounds across several small ingredients and can throw off rise time or flavor balance.
- Ignoring how an ingredient is packed. Brown sugar pressed firmly into a teaspoon weighs more than granulated sugar spooned loosely, so packed versus level instructions in a recipe change the real gram weight even for the same ingredient.
