A list of most of the conversions can be found in the Notes section of [ reprap.org ] with quantities of each specified in [ reprap.org ---Rant begins----Slight correction to the previous post: according to the CIA factbook (via wikipedia [ en.wikipedia.org ]) aside from the US it is only *almost* the rest of the world that uses metric: Burma (Myanmar) and Liberia are bucking the trend as well at the moment plus the US military has been using metric for a long time :-)So, outside of the US: "standard" length measurements means metric and ironically what you want is more widely known as "imperial units" (http://en.wikipedia.org/wiki/Imperial_units) taken from the fact that they were used by the British Empire that your forefathers wanted to cut ties with :-) (with interesting differences between US and British measurements introduced mainly in units of volume and mass)BTW, For a window into why the rest of the world thinks metric is better, try understanding the Burmese system [ en.wikipedia.org ---Rant ends---Anyway, history and jargon aside, in 1959 the yard was redefined as exactly 0.9144m meaning an inch is exactly be 2.54cm or 25.4mm so if you want you can do an exact conversion and then find the closest fit to your "standard" measurements (which is essentially what the SAE design is). Most parts are designed so that there is a good fit between standard metric and US nuts and bolts sizes so it isn't too much of a problem but pay attention to the size of nuts and the holes for them when looking at the trapped nuts.
