In this first volume, all the various measures used in practice, more especially by engineers and physicists, are given with their values in terms of as many of the others as they are likely to be converted into in practice; the reciprocals of these are also given, thus enabling every calculation involving the conversion of one measure into another to be reduced to a single, simple multiplication.
