How Oxygen kg to Liters Converter Works?
The Oxygen kg to Liters Converter works in 3 steps.
- 1
Enter the mass of oxygen in kilograms (kg).
- 2
Keep 0.001429 kg/L for oxygen at standard temperature and pressure (STP), or use 0.001331 kg/L for 20 °C (68 °F).
- 3
Read the gas volume in liters (L); medical flow rates in L/min divide straight into this number.
Oxygen kg to Liters Converter Formula
The Oxygen kg to Liters Converter formula is:
Volume (L) = Mass of oxygen (kg) ÷ 0.001429 kg/LThe reverse formula is Mass (kg) = Volume of oxygen (L) × 0.001429 kg/L.
Worked example
1 kg (2.2 lb) of oxygen ÷ 0.001429 kg/L = 699.8 L (184.9 US gal, 0.6998 m³).
Liquid oxygen is 1.141 kg/L, so 1 L of liquid oxygen boils into about 860 L of gas at 20 °C. Hospitals store oxygen as a liquid in vacuum-insulated evaporators (VIEs).
Oxygen kg to Liters Converter Conversion Table
The Oxygen kg to Liters Converter table converts 10 masses of oxygen from 0.01 kg (10 g) to 50 kg (110.2 lb) into liters (L), cubic meters (m³) and cubic feet (ft³) at a gas density of 1.429 g/L (1.429 kg/m³).

What is Oxygen kg to Liters Converter?
The Oxygen kg to Liters Converter is a calculator that converts oxygen (O₂) from mass to gas volume at 1.429 g/L. Oxygen is about 10% heavier than air and supports combustion.
Medical oxygen cylinders state the gas volume at 1 atm, not the internal volume. A CD-size cylinder holds about 460 L of gas, or about 0.61 kg of oxygen.
What are the uses of Oxygen kg to Liters Converter?
There are 4 main uses of the Oxygen kg to Liters Converter: medical supply, welding and cutting, aquaculture and space and diving.
Medical supply
Clinicians convert cylinder kg into hours at 2 L/min.
Welding and cutting
Fabricators convert oxygen cylinder mass into cutting time.
Aquaculture
Fish farms convert liquid oxygen mass into gas for aeration.
Space and diving
Engineers convert oxygen mass into breathing gas volume.
