that's a question everyone struggles with however I have come to an understanding after much deliberating and research...
For CS I treat the us figure as the actual PPM. So if you are getting 14us, I would take that as 14ppm. this would show on your meter as 7ppm. I do brew the CS to around 30us sometimes, but to be honest it hits a wall around there, and I do not think its the best stuff..... I would keep it to around 12-20us (6-10 ppm). Regards.

I know that almost all people are reading the ppm number off a tds meter that's calibrated for table salt, getting people to understand calibration is a losing battle. I just picked up a batch that's been sitting around for a while and it reads 14 uSeimens, so for that batch what should I tell them? Or do I just do like the eBay marketers and make up a number?
