    Ladies and Gentlemen
    Please allow me to share a personal testimonial regarding the “International System Ruler.” As a high school chemistry and physics teacher I devise lessons that require my students to develop their own inquiry labs with the caveat that they must record their measurements using the US customary and SI units. I then pose a question about their measurements that must be answered in the shortest period of time possible. Of course we know what will happen. The students invariably choose the SI system to answer the question because of the ease of problem solving, accuracy and they save time.
    Now for a follow-up I provided one group of students with a ruler with inches and centimeters and another with the International System Ruler. The requirement was to use the SI units and simply change a given value of distance from centimeters to kilometers, then to nanometers etc.. Of course those students without the ISR were at a distinct disadvantage and voiced this concern loudly and instantly. So now those students that do exceptionally well on a lab are rewarded with a ISR. Oh, by the way, the science teachers all want them now too!
    Thank you for allowing me to share
    Greg Whatley, MAT, RPh.

    This ruler is not the “firm” type, but rather the “flimsy” sort of “wobbley” type of ruler that is similar to a hard construction paper type material…only plastic. That is not necessarily a bad thing though, it just changes the purpose of the ruler. This ruler makes a good book mark too, that you can later whip out and use for measuring things in the far more useful metric of centimeters (rather than inches of course!). I wouldn’t necessarily buy more than one (unlike the Liter Cube, definitely get a COUPLE of those!!), but one around the house will definitely come in handy here and there.

    Enjoy my fellow Metricteers!
