Convert grams to teaspoons for 20+ cooking ingredients — spices, sugar, salt, and more
💡 Why This Matters At teaspoon scale, precision really counts — spices, salt, and leaveners are measured this small precisely because a little goes a long way. Pick your ingredient, enter the grams, and get an accurate teaspoon measurement without guessing.
A teaspoon of honey weighs about 7g, but a teaspoon of rolled oats weighs under 2g — nearly 4x lighter, despite filling the exact same spoon.

A US teaspoon is a fixed volume — about 4.93 ml — but its weight in grams depends on the ingredient's density. This converter divides the grams you enter by that ingredient's grams-per-teaspoon figure (derived from its grams-per-cup density, since 1 cup = 48 teaspoons) to give you an accurate teaspoon measurement.
The teaspoon figure reflects a standard, level teaspoon using each ingredient's conventional measuring method. At this small scale, small differences matter more proportionally — a slightly rounded teaspoon of baking powder or salt can shift the actual gram amount by 15-20%, which is significant when the recipe only calls for a teaspoon or two total.
These are standard density averages, not exact for every brand — spice grind, salt crystal size, and how firmly a powder is packed all shift real weight somewhat. For very precise work (some pastry and confection recipes specify gram-exact leavener amounts), a small digital scale that reads to 0.1g is worth the investment.
Useful for converting nutrition-label or medical-dosage gram amounts into a kitchen-usable spoon measurement, or checking a small precise gram quantity from a recipe against your measuring spoons. For anything under 5g, consider weighing directly if your scale supports it.
Example: Say a recipe calls for 10g of baking powder and you only have measuring spoons. Baking powder is 4g per teaspoon, so: 10 ÷ 4 = 2.5 teaspoons. For 10g of table salt instead: 10 ÷ 5.69 = 1.76 teaspoons — same weight, less volume, because salt is denser.
It depends on the ingredient. A US teaspoon is a fixed volume (about 4.93 ml), but a teaspoon of salt weighs almost twice as much as a teaspoon of rolled oats because salt is denser.
Because spices, leaveners, and salt are used in small quantities, even a small gram error is a large percentage error. A rounded vs. level teaspoon of baking powder can meaningfully change how a baked good rises.
No — a dessert spoon is roughly twice a teaspoon (about 10 ml versus 4.93 ml). If a recipe says dessert spoon, don't substitute a teaspoon 1-for-1.
