Just how much do you really know about the metric system? Test your SI (International System of Units) savvy with 61 self-correcting questions. (Editor/RK)

Using the triple beam balance to measure mass in metrics is just one of the many skills teachers want their students to master. The author has found a few effective and fun approaches to develop this skill over a couple of interesting days. With each activity, students are actively involved in the construction of knowledge: What is mass and how is…

By the time students reach a middle school science course, they are expected to make measurements using the metric system. However, most are not practiced in its use, as their experience in metrics is often limited to one unit they were taught in elementary school. This lack of knowledge is not wholly the fault of formal education. Although the…

H. Blanton and J. Jaccard examined the arbitrariness of metrics in the context of 2 current issues: (a) the measurement of racial prejudice and (b) the establishment of clinically significant change. According to Blanton and Jaccard, although research findings are not undermined by arbitrary metrics, individual scores and score changes may not be…

This booklet is designed to aid product service companies in finding out about the meaning of the metric system for their unique circumstances and to help them phase-in metric servicing smoothly. First is a brief discussion of what the law says about metrics and what the metric system is. Then what is involved in going metric is discussed in…

Metrication and the process of metric changeover in the United States are discussed; preferred terms and units of measure are specified. (DT)

An energy scale, constructed in terms of the Joule, is presented. It provides for the conversion of all traditional units employed in engineering, science, and technology to describe forms of energy; gives the energy associated with physical phenomena; and provides energy equivalents of quantities associated with various energy sources. (DT)

Discusses library facilities and equipment in metric measurements. (JG)

A table lists the following quantities in imperial units, old metric units, and SI units: mass, force, energy, torque, power, pressure, temperature, thermal conductivity, frequency, dynamic viscosity, and kinematic viscosity. (MLH)

This pamphlet gives definitions and symbols for the basic and derived metric units, prefixes, and conversion factors for units frequently used in water resources. Included are conversion factors for units of area, work, heat, power, pressure, viscosity, flow rate, and others. (BB)

The purpose of this pamphlet is to provide a starting point of information on the metric system for any concerned or interested reader. The material is organized into five brief chapters: Man and Measurement; Learning the Metric System; Progress Report: Education; Recommended Sources; and Metrication, American Style. Appendixes include an…

This is the fifth in a series of reports from the U. S. Metric Study, conducted by the National Bureau of Standards, designed to cover the nonmanufacturing segment of the economy representing about 65 percent of the total U. S. employment: mining, agriculture, forestry, fisheries, construction, transportation, communications, utilities,…

This document reviews the debate between 1790 and 1968 on the question of the adoption of the metric system of weights and measures by the United States. Legislative activities involving the metric system and campaigns for and against adoption of the metric system are reviewed. Significant investigations of the question by both public and private…

This paper gives a brief history of measurement systems and of the controversy surrounding the adoption of the metric system as the standard system in the United States. The metric study called for by legislation in 1968 is described, and recommendations for a coordinated national program to change to the metric system are outlined. Some…
