What Is Liquid Nitrogen Conversion?
Liquid nitrogen conversion is the process of converting liquid nitrogen (LN₂) between different units of measurement, including liters, gallons, kilograms, pounds, standard cubic feet (SCF), and normal cubic meters (Nm³). These conversions are essential for cryogenic storage, industrial gas supply, transportation logistics, and engineering calculations.
Because nitrogen can exist as both a cryogenic liquid and a compressed gas, engineers often need to calculate how much gas volume can be generated from a given quantity of liquid nitrogen or determine the liquid storage capacity required to supply a specific gas demand.
Use the liquid nitrogen conversion calculator above to instantly convert between gas and liquid nitrogen units for industrial and scientific applications.

Liquid Nitrogen Conversion Factors
The following reference values are commonly used throughout the industrial gas industry.
Actual values may vary slightly depending on temperature, pressure, and reference standards used.
How to Convert Liquid Nitrogen to Gas Volume
One of the most common calculations is determining how much gaseous nitrogen is produced when liquid nitrogen vaporizes.
Liquid Nitrogen to Nm³ Formula
Gas Volume (Nm³) = Liquid Volume (L) × 0.694
Example:
- 1,000 liters LN₂ × 0.694
- = 694 Nm³ nitrogen gas
Liquid Nitrogen to SCF Formula
Gas Volume (SCF) = Liquid Volume (L) × 24.8
Example:
- 1,000 liters LN₂ × 24.8
- = 24,800 SCF nitrogen gas
Liquid Nitrogen Expansion Ratio
Liquid nitrogen expands approximately 694 times when it changes from a liquid to a gas.
| Liquid Nitrogen | Equivalent Gas Volume |
|---|---|
| 1 L | 0.694 Nm³ |
| 100 L | 69.4 Nm³ |
| 1,000 L | 694 Nm³ |
| 10,000 L | 6,940 Nm³ |
The 1:694 expansion ratio is widely used for cryogenic tank sizing, nitrogen supply calculations, vaporizer selection, and industrial gas storage planning.
