Re: Voyagers width Message #3 Posted by Gerson W. Barbosa on 12 Dec 2012, 11:21 p.m., in response to message #2 by Walter B
Hallo Walter,
The first value was read on the Vernier inch scale and the second one on the millimeter scale. The latter should be more accurate, since the divisions are closer to each other. Anyway, what I can read is 3 9/64" and 7.98 mm, which are equivalent to 3.14" (with three significant digits at most -- the value 3.1417 was fanciful, of course). I measured two HP-15C units (from 1983 and 1989, respectively), having found the same results (both definitely greater than 3 1/8"). But you're right: more measurements should have been made. Also, perhaps I should use a decent instrument instead of this cheap one (Made in PRC :-)
Cheers,
Gerson.
