Yes consistency is important. Also, the units (and names) whe choose here will apply to all 'plugins' that ppl design for the sim. So for instance if you want to add a pump plugin, you'll have to write data in lph vs mH2O.
Ohms is an universal impedance unit IIRC. During my thermics courses i remember being told that thermal circuits work just like electrical circuit, as per the 'similarity' physics law. Thus thermal impedance has the same 'value' as electrical impedance, Ohms, as they both represent a potential divided by a current.
Now °C/W is maybe not *exactly* a thermal impedance, but it looks like it's very close. My memories are too distant to remember the units involved but a quick google would help for that. (i'm at work right now)
As for mH20 it's quite a standard actually. Numbers are not so small, my pump produces 1.95mH2O of head for example. If ppl really want to we could use cmH2O (centimeters) so 1.95mH20 becomes 195cmH20. I presume most fittings will have backpressures in the orders of a few cmH20.
Up to you guys, what are your thoughts.
(edit) impedance ? resistance? i'm not sure about the english term here.
electrically: U=RI -> R is the 'resistance' (in French), does that translate as an impedance ?
In French 'impedance' is the complex value of 'resistance', called Z and is Z=a+ib (complex number)
