Imperial to Metric conversion
Following on from my suggestings of yesterday with regards to design for manufacture, an interesting idea suggested on the Model Engineering Clearing house forum
using 25.6 as a conversion factor makes 1/32″ = 0.8mm rather than .079375mm which you get if you use 25.4, 3/16th” = 4.8mm rather than 4.7625mm etc., etc., etc. Much, much easier, and you get a bigger loco!
i faced the fractional conversion problem and decided to make my own calculator check it out! it does fractions 2/4/8/16/23/64
