Why grams-to-tablespoons needs both density and convention
Grams measure weight, while tablespoons measure volume. To convert between them you need the ingredient density and the size of the tablespoon itself. If the ingredient is honey, one tablespoon weighs far more than if the ingredient is flour. If the recipe uses Australian tablespoons, the spoon is also larger than a US or metric tablespoon.
That means a reliable grams-to-tablespoons converter cannot use one fixed ratio. The tool first picks the tablespoon size, then applies the ingredient density to determine how many tablespoons that gram weight represents.
Tablespoons = Weight (g) ÷ Density (g/tbsp)
The selected tablespoon convention changes the density basis used in the conversion.
1 US tbsp ≈ 14.79 ml; 1 metric tbsp = 15 ml; 1 Australian tbsp = 20 ml
Explains why the same gram weight can produce different tablespoon counts across recipe systems.
Teaspoons = Tablespoons × convention-specific tsp equivalence
US and metric tablespoons are about 3 teaspoons; Australian tablespoons are 4 metric teaspoons.
