Measurement of various quantities has been an integral part of our lives since ancient times. In this modern era of automation, we need to measure quantities more so than ever. So, what is the importance of Diffusivity converter? The purpose of Diffusivity converter is to provide Diffusivity in the unit that you require irrespective of the unit in which Diffusivity was previously defined. Conversion of these quantities is equally important as measuring them. Diffusivity conversion helps in converting different units of Diffusivity. Diffusivity, mass diffusivity, or diffusion coefficient is a proportionality constant between the molar flux due to molecular diffusion and the gradient in the concentration of the species.. There are various units which help us define Diffusivity and we can convert the units according to our requirement. unitsconverters.com provides a simple tool that gives you conversion of Diffusivity from one unit to another.
