This is more of an issue for those of us who are still in the hinterlands of the internet i.e. dial-up, where conversion charts aren’t just a click away.

So, I created my own metric conversion chart in MSExcel (any spreadsheet will do ;)) using 1/4″ increments.

The top picture shows the formula and the second picture shows the result of that formula. The conversion numbers for 1/4″ to 61″ fit onto one page when I placed the columns side by side in the spreadsheet.

I printed the sheet and keep it in the front of my Design Binder for quick reference so that when I’m writing up a pattern or drawing a schematic all of the needed conversions are there at a glance.
