How many teaspoons in 780g?

To convert grams to teaspoons, you need to know the substance's density, as different substances weigh differently. For example, granulated sugar is approximately 4.2 grams per teaspoon, while flour is about 2.6 grams per teaspoon. Assuming you're referring to granulated sugar, 780 grams would be roughly 186 teaspoons (780g ÷ 4.2g/teaspoon). For other substances, the conversion would vary.
