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)

Presents the views of a high school physics teacher toward The International System of Units (SI). (HM)

Presents the author's perspective for accepting an approximation to The International System of Units (SI). Some alternatives to the SI form are also presented. (HM)

Looks at what the problems are in the use of quantities and units in chemistry and what has been achieved until this time. Considers quantity and amount of substance, quotients of physical quantities, composition of mixed phases, and equations with quantities. Makes recommendations for future considerations. (CW)

Discusses advantages to the use of SI units in dealing with proportionality problems, with particular emphasis on stoichiometric relationships. A table lists conversion relationships commonly used in chemistry, and a single-step "roadmap" is provided for each relationship. (CS)

Describes a simple exercise that can be used to demonstrate the concepts of SI units, experimental design, and significant digits in a manner that holds the attention of students who already understand these concepts but is still valuable for students who are less prepared. (CCM)

Presents International Standard (SI) units for the field of electrochemistry and magnetochemistry. (SL)

Describes the basics of the International System of Units (SI Units) and specific application of these units in the teaching of chemistry. (MLH)

A useful metrics system for the assessment of the environmental impact of chemical processes is utilized to illustrate several of the principles of green chemistry. The use of this metrics system in conjunction with laboratory experiments in green chemistry would provide for reinforcement in both the theory and practice of green chemistry.

Provides an exercise to help students understand how small atoms are. Also provides a problem to help beginning college students understand the concepts of unit conversions. (JN)

Highlights six papers presented at the Seventh Biennial Conference on Chemical Education (Stillwater, Oklahoma 1982). Topics addressed included history, status, and future of SI units, algebra of SI units, periodic table, new standard-state pressure unit, and suggested new names for mole concept ("numerity" and "chemical amount"). (JN)

SI units come in two distinct types: fundamental (kilogram, meter) and descriptive (atom, molecule). Proper/improper uses of atom/molecule from historical cases are presented followed by a re-introduction of a light "wave (cycle)" unit and the clearly defined photon model which is deduced. Also examines omission of the fundamental unit "radon."…
