Artifact of the Week: Metric Converter

This week’s artifact might familiar to some. It’s a slide rule conversion tool for the metric system. Anyone else have one these lying around? This one belonged to Fred Davis, who worked on the Great Lakes.

  1. I have one of these converters as well copyrighted in 1974. Mine is slightly different where one side has AREA, VOLUME, and MASS. The other side has CAPACITY, LENGTH, and a TEMP conversion scale. I acquired it at the time of the copyright and have kept it all this time.
