1 1/2 Cups of Honey in Grams
1 1/2 cups of honey weighs 510 grams (about 18 oz), based on 340 g per US cup (1 US cup = 240 ml). That's the same as 24 tablespoons of honey. When a recipe's outcome depends on accuracy — especially baking — weigh it instead of measuring by cup.
1 1/2 cups is one full cup plus a half (340 g + 170 g). At this size the fill method starts to matter: the error in each cup is added, not averaged.
