Metric System Demonstration Apparatus -- Reforms 1971-1990

Reforms 1971-1990

A set of seven copper-soldered wooden volumetric measures from largest to smallest, 1 dekaliter (a dekaliter is 10 liters), 1/2 dekaliter (5 liters), 2 liters, 1 liter, 5 deciliters (a deciliter is 1/10 of a liter or 100 cubic centimeters), 2 deciliters, and 1 deciliter.

By 1975, the United States was the only industrialized nation not committed to adopting metric units. Fearing a decline in the nation’s share of international trade, the U.S. Congress endorsed the metric system. Government officials planned a program of voluntary conversion to metric units that was to take ten years. Many Americans disliked the unfamiliar measures and, in the 1980s, President Reagan sharply reduced funds for metric programs. Meanwhile, metric units had been widely adopted in some industries.
