Whiskey (40% ABV) Grams to Fluid Ounces

Updated: July 28, 2026 · Source: 40% ABV ethanol-water density approximation (Whiskey density near 40% ABV.)

Snapshot

1 gram of whiskey (40% abv) equals 0.04 fluid ounces. Conversion Encyclopedia keeps one fixed beverage basis on this page so the calculator, common values, and reverse page stay aligned.

Reference basis: 0.948 g/mL.
Example: 250 g = 8.92 fl oz.
This uses Whiskey (40% ABV) at 40% ABV (not pure ethanol), so density differs from alcohol-only references.

Full API documentation

Explanation

Convert grams of whiskey (40% abv) into US fluid ounces using the same 28.04 grams-per-fluid-ounce reference used on the reverse page.

That is especially useful for cocktail specs, batching sheets, and inventory work where whiskey (40% abv) starts from weight but service still uses poured measures. Whiskey (40% ABV) is treated here as 40% ABV, so stronger or lower-proof bottles can shift the practical density slightly.

Method & Density Basis

Density basis: 0.948 g/mL (anchored to US cup 236.588 mL and US fl oz 29.57 mL).
Applied factor: 1 Gram = 0.04 Fluid Ounces.
Consistency rule: mirror pages invert the same per-liquid constants so forward and reverse directions remain aligned.
Source: 40% ABV ethanol-water density approximation (Whiskey density near 40% ABV.)

Methodology

Whiskey (40% ABV) density evidence

Whiskey (40% ABV) uses 0.948 g/mL in this dataset, which is 5.2% lighter by volume than the 1 g/mL water reference. Evidence status: medium-confidence. Source basis: Whiskey density near 40% ABV.

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.
