1 gram of guinness equals < 0.01 cups. Conversion Encyclopedia keeps one fixed beverage basis on this page so the calculator, common values, and reverse page stay aligned.
- Reference basis: 1.01 g/mL.
- Example: 250 g = 1.05 cups (about 1 cup).
- Source basis: Beer density approximation.

SwitchExplanation
Convert grams of guinness into US cups using the same 238.95 grams-per-cup reference used on the reverse page.
That keeps guinness tied to one density reference instead of switching between generic liquid charts. Guinness can vary a little with formulation and temperature, so the converter keeps one density reference for consistency.
Common Conversion Values
| Grams | Cups |

| 25 | 0.1 (about 1/8 cup) |
| 50 | 0.21 (about 1/4 cup) |
| 75 | 0.31 (about 1/3 cup) |
| 100 | 0.42 (about 3/8 cup) |

| 200 | 0.84 (about 7/8 cup) |
| 250 | 1.05 (about 1 cup) |
| 500 | 2.09 (about 2 1/8 cups) |
Guinness density evidence
Guinness uses 1.01 g/mL in this dataset, which is 1.0% heavier by volume than the 1 g/mL water reference. Evidence status: medium-confidence. Source basis: Beer density approximation near room temperature.
Brand formulation, alcohol or sugar concentration, carbonation, and serving temperature can change the weight of a measured volume. Use this value as a documented reference rather than a producer specification.
