How to convert cell units (c.u.) to mole? If one has values in terms of cell units (c.u.) how may it be converted to $\mu$M? Should I think a "cell unit" as $1\;c.u.= \frac{1}{\text{cell volume}}$ and $1\;c.u.=\frac{1}{\text{cell volume}}*(\text{volume of 1 mole of in 1 atm)} \; Mole$? an example of c.u. units, belongs to this article Thank you.

The paper references c.u. to their "ODE model construction & simulation" which is referenced back to a 2016 paper that uses the term in reference to a simulation in MATLAB.

c.u. is abbreviation for CONCENTRATION UNIT not CELL UNIT.

> Given the absence of experimental measurements of protein concentrations, we use concentration units (c.u.) as unit to represent the relative concentrations of proteins in the model
