Part 1 is an introduction describing the three major world measurement systems: metric (SI), British and American. Part 2 gives a subject-by-subject listing of definitions, special measurements, formulae and calculations for the various subject areas.

In Part 4 are to be found abbreviations, rough conversions and a valuable body of weights and measures used historically and in the countries of the world apart from the UK and USA, as well as a small section on the historic measures of the UK. - Introduction.
