The 2-6/25 is pretty interesting. Strict conversion of the 57 mm gives 2.2441" so it would have been a negligible error to round to 2.25 (2-1/4, using their notation). The inches are only for English-speaking Americans, and the centimeters for Spanish speaking. :)
Why is 57 mm inconvenient? I suppose you would have to open the device to determine whether a "rounder" number like 50 or 60 mm was practical, or had internal interference. It does seem that one dual-labelled drawing would fit on half the paper and provide an obvious cost-save. ________________________________ From: "Ressel, Howard R (DOT)" <howard.res...@dot.ny.gov> To: U.S. Metric Association <usma@colostate.edu> Sent: Monday, February 10, 2014 8:28 AM Subject: [USMA:53546] Interesting mounting template I purchased a GE light for under my cabinet, one of these battery operated LED ones. The mounting template was interesting (see attached). One can speculate a lot here, indeed the measurements are identical but neither is convenient. Did they just plunk down two holes in the back of the mounting plate then measure what the spacing was and call it a day? I wonder why they needed to have two drawings which I did cut and paste on top of each other and verify are identical, the holes line up.
