* Grams measure weight.
* Teaspoons measure volume.
To convert between grams and teaspoons, you need to know the density of the substance you're measuring. For example:
* Sugar: 1 gram of sugar is roughly equal to 0.3 teaspoons.
* Flour: 1 gram of flour is roughly equal to 0.4 teaspoons.
* Water: 1 gram of water is roughly equal to 0.2 teaspoons.
Therefore, you need to specify what substance you're measuring to determine how many teaspoons are equivalent to 2 grams.
