Incorporation of Units into Programming Languages The issues of how a programming language might aid in keeping track of physical units (feet, sec, etc.) are discussed. A method is given for the introduction of relationships among units (a watt is volts*amps, a yard is three feet) and subsequent automatic conversion based upon these relationships. Various proposals for syntax are considered. CACM May, 1978 Karr, M. Loveman III, D.
