Chemistry Everyday for Everyone
Quantity Calculus: Unambiguous Designation of Values and Units in Graphs and Tables
Mary Anne White
Dalhousie University, Department of Chemistry, Halifax, Nova Scotia B3H 4J3, CANADA
Cover
May 1998
Vol. 75 No. 5
p. 607
Abstract
The method of quantity calculus treats physical quantities as the product of a numerical value and a unit. This method, known for more than a century and internationally recommended for handling of physical quantities, is not used as extensively in textbooks and teaching as it could be. This paper gives some background to the methodology, and shows examples, suitable for teaching to undergraduate students, of the use of quantity calculus to provide unambiguous representations of physical quantities in tables and graphs.
