I can’t wait to make something out of wood using Matthias Wandel’s ingenious solution to the greatest division in human society: the Metric and Imperial Unified Ruler.
Metric people like nice convenient units, decimal, and being able to make easy calculations. Inches people like complicated fractional units. So I have come up with a new ruler to unite the two. It has nice millimeter and centimeter sized increments, but uses inches as the scale. I present to you, my new universal fractional ruler! The centimeter and millimeter sized divisions are labeled with fractional inch units.
Not to be confused with fractional rulers [Amazon]; this is much more useish!
