Units of Relative Difficulty?

How is the relative difficulty in this measured? It seems like this should at least be mentioned in the file description, even if it's not shown on the image itself. I assume it's measured in some objective way? 72.28.241.80 (talk) 19:04, 7 January 2015 (UTC)

No measurement is necessary. In Bitcoin#Mining it is mentioned that for every mined block there is a specific difficulty target number. The difficulty target is recorded in every mined block. The relative mining difficulty at any given time is the ratio between the difficulty target at 9 January 2009 and the difficulty target at the given time. This means that the relative mining difficulty at 9 January 2009 is defined as 1. Ladislav Mecir (talk) 20:10, 7 January 2015 (UTC)

Ah, I suppose I missed that part when I was looking over the article. Makes sense, though. 72.28.241.80 (talk) 00:17, 8 January 2015 (UTC)
