To convert teaspoons (tsp) to grams (g), you need to know the density of the ingredient because a teaspoon measures volume while a gram measures mass. The general formula is:
Grams = Teaspoons × Conversion Factor
Where:
Conversion Factor = grams per teaspoon (g/tsp) of the specific ingredient
Density is measured in g/ml and varies by substance
For water, 1 teaspoon weighs approximately 4.93 g, which simplifies the equation to:
Grams of water ≈ Teaspoons of water × 4.93
Part 2: Example Conversion Using Water
Let’s convert 1 teaspoon of water to grams:
Grams = 1 tsp × 4.93 = 4.93 g
Therefore, 1 teaspoon of water is approximately equal to 4.93 grams.
Part 3: Example Conversion Using Sugar
Let’s convert 2 teaspoons of granulated sugar to grams:
Grams = 2 tsp × 4.18 = 8.36 g
Therefore, 2 teaspoons of granulated sugar is approximately equal to 8.36 grams.
Note: The conversion factor is unique to each ingredient because every food has a different density. Always pick the correct ingredient in the calculator above for the most accurate teaspoon to gram result.

Teaspoons Converted to Other Cooking / Baking Measurements
Teaspoons and grams are two of the most common units used in cooking and baking recipes, but converting between them isn’t a one-size-fits-all calculation. A teaspoon is a unit of volume, while a gram is a unit of mass, so the same teaspoon of one ingredient can weigh very differently from a teaspoon of another.
The density of each ingredient determines exactly how many grams fit into a single teaspoon, which is why there is no universal tsp-to-g conversion that works for every food. A teaspoon of honey, for example, weighs roughly 7 grams, while a teaspoon of dried herbs weighs less than 1 gram.
What is a Teaspoon Measurement?
A teaspoon is a unit of volume most often used in cooking, baking, and serving food and medicine. One US teaspoon is equal to 1/3 of a tablespoon, 1/48 of a US cup, or approximately 4.92892 milliliters. A metric teaspoon, used in many other countries, is rounded to exactly 5 milliliters.
The standard abbreviation for a teaspoon is “tsp” (sometimes written as “t” in older recipes).
What is a Gram?
A gram is a unit of mass in the Metric System and the International System of Units (SI). One gram is defined as 1/1000th of a kilogram and is the standard mass unit used on nearly all food packaging worldwide.
The abbreviation for a gram is “g.”

Frequently Asked Questions About Teaspoons to Grams
How many grams are in a teaspoon?
One teaspoon of water weighs approximately 4.93 grams, which is the most common baseline reference. However, the gram weight of a teaspoon depends entirely on the ingredient’s density. A teaspoon of honey weighs around 7.08 g, a teaspoon of salt weighs about 5.69 g, and a teaspoon of dried herbs may weigh less than 1 g. Use the calculator above for ingredient-specific values.
How many grams of sugar are in 1 teaspoon?
One level teaspoon of granulated white sugar weighs approximately 4.18 grams. Brown sugar (packed) weighs slightly more at roughly 4.55 g per teaspoon, and powdered sugar weighs about 4.41 g per teaspoon. Two teaspoons of granulated sugar equal about 8.36 grams.
How many grams of flour are in 1 teaspoon?
One level teaspoon of all-purpose flour weighs approximately 2.60 grams. Whole wheat flour is slightly denser when packed but tends to weigh about 2.44 g per teaspoon, while cake flour is around 3.20 g per teaspoon. For larger flour quantities, a cup (48 tsp) of all-purpose flour weighs roughly 125 g.
How many grams of salt are in a teaspoon?
One teaspoon of fine table salt weighs approximately 5.69 grams. Coarse salts such as kosher salt and sea salt have larger crystals, so they pack less densely. A teaspoon of Diamond Crystal kosher salt weighs only about 2.8 g, while Morton kosher salt is closer to 4.8 g per teaspoon.
Is 1 teaspoon equal to 5 grams?
Not exactly. The “1 teaspoon = 5 grams” rule is a rough kitchen approximation that only works for ingredients with density close to water, such as water, milk, or vinegar. The actual weight depends on the substance: 1 tsp of water = 4.93 g, 1 tsp of honey = 7.08 g, 1 tsp of flour = 2.60 g. Always check the ingredient before assuming 5 g.
How do I convert teaspoons to grams without a calculator?
Use the formula: Grams = Teaspoons × density factor (g/tsp). Multiply the number of teaspoons by the grams-per-teaspoon value for your ingredient. For example, to convert 3 teaspoons of honey: 3 × 7.08 = 21.24 grams. The reference chart above lists density factors for over 100 common cooking and baking ingredients.
How many grams are in 1/2 teaspoon?
A half teaspoon (½ tsp) of water weighs approximately 2.46 grams. Half-teaspoon weights for other common ingredients: salt ≈ 2.85 g, granulated sugar ≈ 2.09 g, baking powder ≈ 1.14 g, all-purpose flour ≈ 1.30 g, and honey ≈ 3.54 g.
How many grams are in 1/4 teaspoon?
A quarter teaspoon (¼ tsp) of water weighs about 1.23 grams. For other ingredients: salt ≈ 1.42 g, granulated sugar ≈ 1.05 g, baking soda ≈ 0.56 g, ground cinnamon ≈ 0.65 g, and ground black pepper ≈ 0.67 g per quarter teaspoon.
Is a US teaspoon the same as a metric teaspoon?
No. A US teaspoon equals approximately 4.93 mL, while a metric teaspoon equals exactly 5 mL. An Imperial (UK) teaspoon is larger still at about 5.92 mL. The difference is small enough that most recipes treat them as equivalent, but precision baking or pharmaceutical dosing should use the correct regional standard.
Why do different ingredients have different teaspoon-to-gram conversions?
Because grams measure mass and teaspoons measure volume. Every ingredient has its own density, so the same volumetric scoop holds a different mass depending on what’s inside. Light, fluffy ingredients like cocoa powder (2.15 g/tsp) weigh far less than dense ones like honey (7.08 g/tsp) or table salt (5.69 g/tsp).
How many teaspoons make a tablespoon, a cup, or a fluid ounce?
In US measurements: 1 tablespoon = 3 teaspoons, 1 fluid ounce = 6 teaspoons, and 1 cup = 48 teaspoons. These conversions are volume-to-volume and remain the same regardless of the ingredient.
