Oh great put the pressure on me now huh? LOL
The manometer I have been thinking about would be based on a meter scale this solves the problem of having equal divisions and its easy to come by. Since a meter has 1000 mm, so if you incline the manometer 4" you have divisions of .004, 5"=.005, 6"=.006 ect. A meter scale will give you an inclined manometer 39.37" in length with 1000 equal divisions, yes you could do the same with a ruler but the 1000 divisions makes it easier I feel with the math. Probably way overkill for the average user having a scale so long? A simple spreadsheet to make the conversions and you are all set. I'll get something worked up in a day or two, might go till after the holiday though. I'll keep the forum posted in a new thread . . .
