Explanation

Convert grams of tonic water into US fluid ounces using the same 29.87 grams-per-fluid-ounce 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.

  • Applied factor: 1 Gram = 0.03 Fluid Ounces.
