Table of Decimal equivalents, the L. S. Starrett Co.

<< >>
Companies seeking to provide customers with advertisements they might consult repeatedly sometimes distributed convenient mathematical tables. This is an example of one of these. The small white plastic card has figures printed in black. The table gives decimal equivalents of parts of an inch ranging from 1/64” to 1” by sixty-fourth-inch increments.
The other side of the card has three small drawings that show products of the L. S. Starrett Co. of Athol, Massachusetts. A mark on that side reads: THE TOOLS MECHANICS BUY (/) STANDARD FOR (/) ACCURACY, WORKMANSHIP, DESIGN, FINISH. A mark on the side of the card with the table indicates that it was made by Sanders Manufacturing Company of Nashville, Tennesee. That company has been in business since 1919.
This table was found in the collections of what was then the Division of Work and Industry at the National Museum of American History.
