How Teaspoon Conversions Work
Volume conversions use a fixed factor. For example, 1 teaspoon = 4.92892 mL exactly.
mL = tsp × 4.92892
Weight conversions depend on the ingredient's density. The formula is:
grams = tsp × 4.92892 × density (g/mL)
Example: 2 tsp of granulated sugar (density 0.845 g/mL)
grams = 2 × 4.929 × 0.845 = 8.33 g
