Liquid Nitrogen weighs 0.808 kg per litre. Convert litres to kilograms (and back) using its exact density.
Quick Metrology Summary
1 liter of Liquid Nitrogen weighs approximately 0.808 kilograms (or 808 grams) at standard room temperature. Because mass equals volume multiplied by density (\(m = V \times \rho\)), multiplying volume in liters by 0.808 gives the exact mass in kg.
Liquid Nitrogen: Weight per Litre Explained
Liquid Nitrogen has a density of 0.808 kg/L, which makes it 19% lighter than water. Liquid nitrogen is boiling at -196°C and weighs 0.808 kg/L as a liquid, about 19% less than water.
When You Need This Conversion
Cryogenic storage of biological samples, food-freezing, dewar filling and laboratory demonstrations.
What Changes the Density
A litre of liquid expands to about 695 litres of gas on warming, so tanks are vented. Density falls slightly as it warms toward its boiling point.
How it works

How to Convert Liters of Liquid Nitrogen to Kilograms
Liquid nitrogen is boiling at -196°C and weighs 0.808 kg/L as a liquid, about 19% less than water. To convert, multiply the volume in litres by 0.808. To go the other way, divide the weight in kilograms by 0.808.
kg = Litres × 0.808
L = kg ÷ 0.808
1 L → 0.808 kg
10 L → 8.08 kg
100 L → 80.8 kgExample
Convert 5 litres of liquid nitrogen to kilograms: 5 × 0.808 = 4.04 kg, or 8.91 lb. Reversed: 4.04 kg ÷ 0.808 = 5 L.
Worked examples
| Scenario | Calculation | Result |
|---|---|---|
| 1 L of liquid nitrogen | 1 × 0.808 kg/L | 0.808 kg |
| 5 L of liquid nitrogen | 5 × 0.808 kg/L | 4.04 kg |
| 20 L of liquid nitrogen | 20 × 0.808 kg/L | 16.16 kg |
| 100 L of liquid nitrogen | 100 × 0.808 kg/L | 80.8 kg |
| 10 kg of liquid nitrogen (reverse) | 10 ÷ 0.808 kg/L | 12.38 L |

About 8.08 kg of nitrogen, plus the vessel.
Because it boils at -196°C, room temperature heat evaporates it continuously and the mass leaves as gas.
1 litre of liquid nitrogen weighs 0.808 kg (808 grams, or 1.78 lb), using a density of 0.808 kg/L.
1 kg of liquid nitrogen is 1.238 litres. Divide the weight by the density: 1 ÷ 0.808 = 1.238.
Multiply the volume by 0.808. For example, 10 litres of liquid nitrogen is 8.08 kg and 50 litres is 40.4 kg.
