Wow... just one question though, what is 86000?
For our case of profitability, the current standard of btc/day per mh/s makes perfect sense, other than being long to express. You simply take your hashrate in mh/s and multiply it by this profitability and you get your expected btc/day.
Yes, and because "btc/day per mh/s" is too long to express, barely anyone uses the proper units in their discussion and it often leads to a semi-retarded conversation.
