The modern ruler or measuring tape hasn’t been innovated enough, or so feels designer Yan-Ting Chen. Especially when it comes to conversion of Metric Units to Imperial (or vice versa), while on the job, it’s tough to pull out the calculator or tax your brains with the mental math. So here’s the solution that will keep your hand steady while mark with the ruler aid and do the centimeters to inches in a jiffy, The E Ink Ruler! I’m not getting into the tech-specs (not been provided!), but for its idea per se I think this is super!
