Mean Free Path Length Calculator

This tool calculates the mean free path length of a molecule in the gas phase. Mean free path is the average distance covered by a molecule before colliding with another molecule.

Type the required values to get the mean free path length:

Viscosity (µ, kg/ms)

Pressure (P, Pa)

Temperature (T, K)

Molecular Weight (M, g/mol) of Gas

Mean free path length (m)
