This online chemistry calculator may be used to calculate root mean square velocity, mean velocity (a.k.a average velocity) and median velocity. Gaseous molecules follow a Maxwell-Boltzmann distribution which is depends on the applied temperature and the molecular weight of the gaseous molecules. To calculate the mean velocity and the median velocity click and choose them on the options menu of velocity.
