2½ Cups to Grams
What two and a half cups weighs, for every common baking ingredient
2½ cups is 313 g of all-purpose flour, 500 g of granulated sugar, or 568 g of butter, using a US cup.
2½ cups of flour and 2½ cups of honey are the same amount of space and nowhere near the same weight. That is why "2½ cups in grams" has no single answer — it needs the ingredient.
It also depends on whose cup the recipe means. A US cup is 236.6 ml; the metric cup used in the UK, Australia, New Zealand and Canada is 250 ml, so it holds about 5.7% more. Both columns are given below.

Why the same cup weighs different amounts
A cup is a fixed amount of space. What that space weighs depends on how densely the ingredient packs into it. Cake flour is 100 g per US cup, granulated sugar 200 g, honey 340 g — so 2½ cups of cake flour weighs 250 g while the same 2½ cups of honey weighs 850 g.
