tsp to Grams Converter
Convert teaspoons to grams for the ingredient you are actually measuring. Enter teaspoons and choose water, sugar, salt, flour, honey, or oil to get grams, milliliters, and ounces — because a teaspoon of flour weighs far less than a teaspoon of salt.
Example: with Teaspoons (tsp) 0.5 · Ingredient (grams per tsp) Water / thin liquid (4.93 g/tsp) → Grams: 2.47 g.
- Volume (mL)2.46 mL
- In ounces (weight)0.087 oz

Grams = teaspoons × grams-per-teaspoon for the ingredient. One teaspoon is 4.92892 mL, so grams per teaspoon is just density times that volume.
Why grams per teaspoon depends on the ingredient
A teaspoon is a fixed volume — 4.92892 mL — but weight depends on how dense the ingredient is. Water fills that spoon with about 4.93 grams. Table salt is dense and packs tightly, so the same spoon holds about 6 grams. All-purpose flour is light and airy, so it manages only about 2.6 grams. That is why swapping a teaspoon of salt for a teaspoon of flour by weight would be a big error.
For baking, weight beats volume every time, because a scooped, packed, or sifted spoon can vary by a third or more. These values are good working averages, but humidity, packing, and brand shift them. When a recipe gives grams, weigh it; the spoon is a convenience, not a precision instrument.
How it’s calculated
Grams = teaspoons × grams-per-teaspoon: water 4.93, granulated sugar 4.2, table salt 6.0, all-purpose flour 2.6, honey 7.0, oil 4.5. Each value is the ingredient density × 4.92892 mL per teaspoon. Milliliters = teaspoons × 4.92892; ounces (weight) = grams ÷ 28.3495.
Grams-per-teaspoon values are approximate and assume level spoons; packing, humidity, sifting, and brand all change the real weight. Weigh ingredients for baking precision.
Grams per teaspoon by ingredient
| Ingredient | Grams per 1 tsp | Grams per 1 tbsp |
|---|---|---|
| Water / thin liquid | 4.93 g | 14.79 g |
| Granulated sugar | 4.2 g | 12.6 g |
| Table salt | 6.0 g | 18.0 g |
| All-purpose flour | 2.6 g | 7.8 g |
| Honey | 7.0 g | 21.0 g |
| Oil | 4.5 g | 13.5 g |
Approximate; grams per teaspoon = 4.92892 mL × density. Values vary with packing, humidity, and brand — weigh for baking precision.
Common mistakes
- Using one grams-per-teaspoon value for every ingredient; salt weighs more than twice what flour does.
- Measuring a heaping or packed spoon when the value assumes a level one.
- Confusing fluid ounces (volume) with ounces of weight — this tool reports weight ounces.
Frequently asked questions
How many grams is a teaspoon?
It depends on the ingredient. A teaspoon of water is about 4.93 g, sugar about 4.2 g, salt about 6 g, and flour about 2.6 g.
What is 1/2 teaspoon in grams?
Half a teaspoon of water is about 2.46 g. Multiply the ingredient's grams-per-teaspoon by 0.5 — half a teaspoon of salt is about 3 g.
Why do salt and flour weigh so differently?
Density. Salt is heavy and packs tight, so a teaspoon holds about 6 g, while airy flour holds only about 2.6 g in the same spoon.
Should I weigh or measure by spoon for baking?
Weigh when you can. A scooped or packed spoon can vary by a third, so grams give far more consistent baking results.
