Units Conversion Nomographs

Many of my clients work in different unit systems.  Because I can't remember all the unit  conversion factors, I have carried around a sheet with the factors for many conversions.  That's fine for creating a spreadsheet or computer program, but is not great when listening to a presentation and someone mentions their well rate or productivity index in different units from the ones in my normal frame of reference.  Stopping the presentation to ask "Wait, is that a lot of GOR or not?" spoils the flow of their presentation.

A few weeks ago someone gave me a sheet with x-y graphs for converting a few values.  That was pretty good because I could convert any amount without using a calculator or spreadsheet.  But, such a sheet could only have a few conversions because the graphs took up too much room.

I tried to improve on that by making a set of nomographs for unit conversion.  I hope this will be helpful to you.

If you find an error or want to request another nomograph, tell me in the comments.
