Max's obj import/export has a scale setting. I have it set for a 10x factor for ZB, so if I export a 2m cube to ZB it comes back to Max as a 2m cube, so even though obj doesn't acknowledge scale the importer/exporter converts the scale to/from Max. As you know, ZB doesnt work in cm so this isn't relevant. Surely there's a…
1 unit, yes, but it's identical to 1cm from Maya according to the tests I've been doing. What a nightmare. I just assumed Maya would have scale options with .obj considering they're both created by the same people. What on earth have Maya users been doing all these years to work between ZB?

zbrush is 1 unit cubed, not 1 cm cubed - an important distinction in this context. To use max terminology I believe Maya has a fixed "system" unit size equivalent to 1 cm - the units option in the settings window appear to be equivalent to the UI units setting in max. obj import/export appears to work on the "system" unit…
