I have a series of ODEs, which were non-dimensionalised using various scalings.

One scaling in particular, was for time, where is the dimensionless variable:

where is in seconds, 0.666 x 10^-16 ml/molecules and = 3.26x10^13 molecules/ml.

I have produced a graph of the non-dimensionalised equations, against and would like to investigate what happens after a period of 5 hours, so would I be right in saying would correspond to 5 hours on my graph? Also can I know read off the current y value on my graph, or does y need to be dimensionalised as well?

Thanks in advance!
