Whiskey (40% ABV) Grams to Milliliters

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

Snapshot

1 gram of whiskey (40% abv) equals 1.05 milliliters. 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 = 263.71 mL.
This uses Whiskey (40% ABV) at 40% ABV (not pure ethanol), so density differs from alcohol-only references.

Full API documentation

Explanation

This converter is built for the density question behind whiskey weight-to-volume conversion, not a generic liquid calculator. It uses a practical room-temperature density estimate of about 0.948 grams per milliliter for whiskey around 40% ABV.

That makes it useful for batching, bottle math, and bar prep when your starting point is spirit weight and you need the matching volume in milliliters. The result is still an estimate, because spirit density can shift slightly with ABV, blend, and temperature.

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 = 1.05 Milliliters.
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.

Questions & answers

Frequently Asked Questions

Does this whiskey converter assume 40% ABV?

Yes. The density used here is for whiskey around 40% ABV at room temperature.

What density of 40% whiskey does this page use?

It uses about 0.948 g/mL for whiskey near 40% ABV at room temperature.

How many mL is 100 grams of whiskey?

Using a density of about 0.948 g/mL, 100 grams of whiskey is about 105.5 mL.

Why is whiskey less dense than water?

Ethanol is less dense than water, so a 40% ABV spirit weighs slightly less per milliliter than water does.
