Full API documentation

Explanation

Convert grams of tonic water into milliliters using the same 1.01 g/mL density 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 = 0.99 Milliliters.
Consistency rule: mirror pages invert the same per-liquid constants so forward and reverse directions remain aligned.

Methodology

Tonic water density evidence

Tonic water 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: Tonic water density 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.
