To convert volumetric flow rate to mass flow rate, you need to know the density of the substance. Multiply the volumetric flow rate (e.g., in m³/s) by the density (e.g., in kg/m³) of the substance. This gives you the mass flow rate in units like kg/s. The formula is Mass Flow Rate = Volumetric Flow Rate x Density.
