# Nondimentional Diffusion Equation

Hello, Here is my problem: I need to turn my time dependent neutron diffusion equation into dimentionless one.. So, I have a couple of questions:

1. As neutron flux is a : "A measure of the intensity of neutron radiation in neutrons/cm2-sec" per definition, is "neutron" a unit? If yes, then:

2. A combination of what quantities, when multiplied with neutron flux, will give me a nondimentional neutron flux?

Any hints are greatly appreciated! Thank you!
