What is oxygen's viscosity?

Oxygen, in its gaseous state at standard conditions (0°C and 1 atm), has a viscosity of approximately 0.0181 mPa·s (millipascal-seconds). This value can vary slightly with temperature and pressure. In its liquid state, the viscosity is considerably higher, around 0.3 mPa·s. Overall, oxygen's viscosity is relatively low compared to many other liquids and gases.
