tsp to grams Converter
Using the tsp to grams converter, you can find the grams equivalent of any item for any specific teaspoon measure.
1 tsp of…
| Substance | Density | 1 tsp weighs / measures |
|---|---|---|
| Water | 1 g/ml | 4.9289 g |
| Milk (whole) | 1.03 g/ml | 5.0768 g |
| Flour (all-purpose) | 0.529 g/ml | 2.6074 g |
| Sugar (granulated) | 0.845 g/ml | 4.1649 g |
| Butter | 0.911 g/ml | 4.4902 g |
| Vegetable oil | 0.92 g/ml | 4.5346 g |
| Honey | 1.42 g/ml | 6.9991 g |
| Table salt | 1.217 g/ml | 5.9985 g |
| Rice (uncooked) | 0.85 g/ml | 4.1896 g |
Why teaspoon (US) to gram needs a substance
Teaspoon (US)s measure volume and grams measure weight, so there is no single conversion factor between them. What bridges the two is density — how much a given volume of that particular substance weighs:
mass = volume × density
Water is the easy case: it is almost exactly 1 g/ml, so 1 ml of water weighs 1 g and the numbers look identical. Nothing else behaves that way — flour is about half as dense, and honey is nearly half again as dense.
Using this for recipes
Pick the ingredient from the list and the conversion uses a typical density for it. Dry ingredients are the least predictable: scooping flour straight from the bag can pack in 20% more than spooning it in gently, which is exactly why baking recipes prefer weights. If you have a density from a supplier or a label, choose Custom density and enter it.
Densities here are typical values for guidance. For anything where precision matters, weigh it.
