⅖ Cup to Grams
What two fifths of a cup weighs, for every common baking ingredient
⅖ cup is 50 g of all-purpose flour, 80 g of granulated sugar, or 90.8 g of butter, using a US cup.
⅖ cup of flour and ⅖ cup of honey are the same amount of space and nowhere near the same weight. That is why "⅖ cup 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 ⅖ cup of cake flour weighs 40 g while the same ⅖ cup of honey weighs 136 g.
