Why can't I convert cups to grams with one number?

Cups measure volume, grams measure weight. A cup of flour is about 125 g, a cup of sugar 200 g and a cup of honey 340 g — it depends on the ingredient.

A US cup is 236.6 ml (usually rounded to 240 ml). Australia, New Zealand and Canada use a 250 ml metric cup, Japanese and Korean recipes use 200 ml, and most of Europe weighs instead.

How many grams is a tablespoon?

A tablespoon is 15 ml. For water that's 15 g, for flour about 8 g, for sugar about 13 g and for honey about 21 g.
