How many cups is 100g of golden syrup?
100g of golden syrup is
⅓ cup
That's 0.32 US cups, 0.30 metric cups, or 5 level tablespoons.
Worked out from 1 US cup = 317g. Cups are rounded to the nearest kitchen fraction, with what's left over in level tablespoons. If you have scales, weighing is more accurate.
Golden syrup is thick and sticky, so a cupful clings to the cup. Weighing it straight into the bowl is more accurate than measuring by volume.

Where these numbers come from
Food Standards Australia New Zealand, Specific gravities (nutrition panel calculator), checked 2026-10-25. USDA doesn't measure this ingredient, so we use this source instead. It lists:
- Syrup, golden: specific gravity 1.34. FSANZ describes its table as indicative, a guide rather than an exact measurement.
Cup and spoon weights are that density (in g/ml) multiplied by the volume: a US cup holds 236.6ml and a US tablespoon 14.8ml. The teaspoon is a third of the tablespoon. Metric-cup figures assume a 250ml cup, and Australian tablespoons hold 20ml. Weights under 10g are rounded to 0.1g, everything else to the nearest gram. Full source list.
