This standard provides conversion factors for units of measurement for a number of quantities, which are, or have been, in general use in engineering, industry and trade. The subjects covered are, broadly, metrology, mechanics and heat; the standard does not deal with purely electrical units.

NOTE1 SI units are normally recommended. However, in certain circumstances use of particular units is required by legislation.

NOTE2 Electrical and light units are given in BS5775‑5 and in BS5775‑6, respectively.

NOTE3 A commentary on imperial and metric systems of measurement and units is given in Annex A.
