With 1 gram of Guinness, you get just a small pour.

Explanation

Convert grams of guinness into milliliters using the same 1.01 g/mL density 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.

Method & Density Basis

  • Density basis: 1.01 g/mL (anchored to US cup 236.588 mL and US fl oz 29.57 mL).
  • Applied factor: 1 Gram = 0.99 Milliliters.
  • Consistency rule: mirror pages invert the same per-liquid constants so forward and reverse directions remain aligned.
