Slide Chart, Metrics Made Easy

<< >>
Description
In the 1970s, after metric units of measure had been adopted in Canada and Great Britain, some people in the United States advocated adoption of the metric system. A variety of special tables were made to help Americans convert between systems of measurement. This slide chart is one of them.
The paper cardboard sleeve is joined with adhesive and printed in red, yellow, pink, black and white. The front contains a table for converting inches to millimeters, another for converting pints to liters, a third for converting feet to meters and a fourth for converting gallons to liters. The reverse has tables for miles/kilometers, ounces/grams, pounds/kilograms and oF/OC.
A mark on the front reads: Metrics (/) made easy. Another reads: INCH/METRIC DIGITAL DIAL (/) A product of (/) Danatron (/) Corporation (3198 ‘C’, Airport Loop Drive, Costa Mesa, CA 92828. A mark on the edge of the slide reads (as best as can be deciphered): Copyright 1977 Nelson Taxel Woodmere N.Y. 11598 Printed in U.S.A.
The object was found in the collections of the Division of Work and Industry of the National Museum of American History.
