With 1 gram of Tonic water, you get < 0.01 cups, which is too little to measure reliably in a cup.

Explanation

Convert grams of tonic water into US cups using the same 238.95 grams-per-cup reference used on the reverse page.

That is useful for mixer prep, dilution planning, and packaged-drink workflows where tonic water volume and weight need to stay comparable. Tonic water can still vary a little with sugar level or carbonation, so the converter keeps one reference value 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 = < 0.01 Cups.
  • Consistency rule: mirror pages invert the same per-liquid constants so forward and reverse directions remain aligned.
