"Closest kitchen measure" rounds down to the nearest standard cup size, then makes up the rest in tablespoons, to the nearest half tablespoon.

Where this number comes from

The weight is taken from the USDA FoodData Central SR Legacy record "Nuts, hazelnuts or filberts" (FDC ID 170581), portion "1 cup, whole" = 135 g. US cups are 236.59 mL. A metric cup (250 mL) holds about 143 g, and a UK imperial cup (284 mL) about 162 g.

Real kitchens vary. Brand, humidity, how finely something is ground and how hard you pack the cup can all move the weight by 5–15%. If a recipe author gives grams, use their number.
