The tape measure I have numbers every centimeter, but has little marking lines for each millimeter. (There isn't ROOM to number every millimeter, but, I agree, if the first centimeter was "10" and not "1" that would be better.) For those of us who know metric, converting cm to mm in our heads is trivial. For those thinking of cm as the "metric inch" it would be a real difficulty.

Why aren't all the 16ths and 32nds numbered on my Customary tapes? Obviously, space is limited and various space saving techniques are adopted. I have seen a (very) few tapes marked in millimeters (every 10 mm with the final zero). My dual tape is annoying. The Customary side is "all inches" to 192" with the inches that are even feet in an alternate color. The metric side is 1 - 99 cm, then a meter mark in alternate color, then 1-99 cm again. The problem is that the nearest meter mark can be 0.5 m away, and when measuring, it is a slightly problem to see what meter you are within. That annoys me far more than the centimeter numbering.

And my mac computer calculator only converts to cm and not mm? Id put my money on the sun and solar energy. What a source of power! I hope we dont have to wait til oil and coal run out before we tackle that. I wish I had a few more years left. -- Thomas Edison♽☯♑
