Scale Weight Scale Reel

Scale Weight Scale Reel
In mm size what would this be 32 swg, basically I am looking for very thin wire for building scale models.?

The wire is galvanised, but could be any type of metal from steel to brass, I do NOT want this on a drum or reel, it has to be very straight, this was for sale its 7 inches in length and 32 swg, I dare say its by weight rather then how round this is, I want something about a quarter of a mm or point 25, everything I;ve tried come up 25mm or 25 of somthing else .25 a quarter in straight lengths.

The scale you need is here :
