Ethanol (Pure Alcohol) weighs 0.789 kg per litre. Convert litres to kilograms (and back) using its exact density.
Quick Metrology Summary
1 liter of Ethanol (Pure Alcohol) weighs approximately 0.789 kilograms (or 789 grams) at standard room temperature. Because mass equals volume multiplied by density (\(m = V \times \rho\)), multiplying volume in liters by 0.789 gives the exact mass in kg.
Ethanol (Pure Alcohol): Weight per Litre Explained
Ethanol (Pure Alcohol) has a density of 0.789 kg/L, which makes it 21% lighter than water. Pure ethanol is about 21% lighter than water. At 0.789 kg/L it is the reason strong spirits weigh less per litre than beer or wine.
When You Need This Conversion
Distillery output and excise calculations, fuel-ethanol blending, laboratory solvent use and hand-sanitiser manufacture.
What Changes the Density
Mixed with water, ethanol's density depends on strength in a slightly non-linear way: 40% ABV spirits are about 0.935 kg/L, and 70% is about 0.886 kg/L.
How it works

How to Convert Liters of Ethanol (Pure Alcohol) to Kilograms
Pure ethanol is about 21% lighter than water. At 0.789 kg/L it is the reason strong spirits weigh less per litre than beer or wine. To convert, multiply the volume in litres by 0.789. To go the other way, divide the weight in kilograms by 0.789.
kg = Litres × 0.789
L = kg ÷ 0.789
1 L → 0.789 kg
10 L → 7.89 kg
100 L → 78.9 kgExample
Convert 5 litres of ethanol (pure alcohol) to kilograms: 5 × 0.789 = 3.945 kg, or 8.7 lb. Reversed: 3.945 kg ÷ 0.789 = 5 L.
Worked examples
| Scenario | Calculation | Result |
|---|---|---|
| 1 L of ethanol (pure alcohol) | 1 × 0.789 kg/L | 0.789 kg |
| 5 L of ethanol (pure alcohol) | 5 × 0.789 kg/L | 3.945 kg |
| 20 L of ethanol (pure alcohol) | 20 × 0.789 kg/L | 15.78 kg |
| 100 L of ethanol (pure alcohol) | 100 × 0.789 kg/L | 78.9 kg |
| 10 kg of ethanol (pure alcohol) (reverse) | 10 ÷ 0.789 kg/L | 12.67 L |
