Enter a mass and choose an ingredient to see teaspoons. Rounding options help match real measuring spoons.
How to use this calculator
- Enter the mass in grams.
- Select an ingredient to auto-fill a typical density. For best precision, measure and use a custom density.
- Choose the teaspoon standard (US or metric).
- Set how many decimal places to display. Optionally round to a practical measuring step.
- Hit Calculate to see exact and rounded teaspoons.
Densities are approximate and influenced by packing, temperature, and brand. For critical work, measure volume directly.
Example data

FAQs
1) Why does this conversion need density?
Because grams measure mass and teaspoons measure volume. The link is density (g/mL), which differs by ingredient and packing.
2) Which teaspoon size is correct?
There are two common standards: US 4.9289 mL and metric 5 mL. Choose the one relevant to your measuring spoons or recipe source.
3) How accurate are the built‑in densities?
They’re typical references. Brand, granularity, humidity, and packing pressure change density. For best accuracy, measure a known volume and compute mass ÷ volume.
4) Can I enter my own density?
Yes. Fill “Custom density” to override the selected ingredient.
5) What does “Round to nearest ¼ tsp” mean?
The exact decimal is rounded to the closest step you choose, making it easier to match available measuring spoons.
6) Why do results differ from online tables?
Tables often assume a single density or teaspoon size. This tool lets you control both factors explicitly.
7) Is this suitable for lab work?
For scientific or baking precision, prefer weight-based recipes or measure volumes directly with calibrated equipment.
