Abstract

A tachymeter (ta kim‘ i ter) is a scale on certain chronograph watches that enables one to calculate speed, where “speed” is the amount of work done in one hour. The work can range from covering a certain distance to manufacturing a number of items. With x as the number of seconds/task and using the equation y = 3600/x, some convenient values of y are placed around the watch dial.
