Convert grams of any liquid to milliliters. Most common liquids have densities near 1.00 g/ml. Free online liquid converter.
Most common liquids — water, milk, vinegar, juice — have densities close to 1.00 g/ml. This means for most liquids, grams and milliliters are roughly the same number. But "roughly" isn't always good enough.
Oils, syrups, and alcohols have noticeably different densities. Honey is 1.42 g/ml; olive oil is 0.92 g/ml; alcohol is 0.79 g/ml. For any liquid conversion, use our gram to ml converter with the correct ingredient selected.
The general formula is: ml = grams ÷ density. For water-like liquids, the density is close to 1.0, so grams ≈ ml. For thicker or lighter liquids, you need the specific density.
Volume [ml] = Mass [g] ÷ 1 [g/ml] Mass [g] = Volume [ml] × 1 [g/ml] Quick reference table for converting liquid between grams and milliliters (density: 1 g/ml).

Grams (g) measure <strong>weight</strong>. Milliliters (ml) measure <strong>volume</strong>. To convert between them, you need the <strong>density</strong> of the substance. This converter does it instantly.
Select from 17 common cooking and baking ingredients - or enter a custom density value for any substance.
Pick the weight unit (grams, kg, oz) and volume unit (ml, liters, cups) you need for the conversion.
Enter a value in either field and the calculator instantly converts it. Works both ways - gram to ml or ml to grams.
Only for water (density 1.00 g/ml). Most common liquids are close — milk (1.03 g/ml), vinegar (1.01 g/ml), juice (~1.05 g/ml). But oils (~0.92 g/ml) and honey (1.42 g/ml) are noticeably different.
For casual cooking with water-based liquids, yes. For oils, syrups, alcohols, or any precision work, no — you need the actual density.
Honey is the densest common cooking liquid at about 1.42 g/ml. Maple syrup (1.33 g/ml) and molasses (1.41 g/ml) are close behind.
Pure ethanol has a density of about 0.79 g/ml — lighter than water. Beer, wine, and spirits vary based on alcohol percentage and dissolved sugars.
