Export Persona: Absolute Size Units

[Mark Oehlschlager]

Within the Export Persona, for individual export slices, I assume that 1x, 2x, and 3x are scaling factors for the pixel dimensions of the art to be exported (i.e., that a 64x64 px image would go out as 64x64, 128x128, and 192x192. But I'm unfamiliar with the absolute units expressed below (see attached image). 

Would someone please explain the meaning of those absolute unit abbreviations and what effect they have on size of the exported slices?

Thanks.

James Ritson's tutorial on Export Persona, starting at about 3:07 mark, he explains those.

@Ron P.

Thanks. Hopefully Serif can get around to spelling that out in the online help files.
