Precise conversion of inch and metric sizes on engineering drawings Ingestion-build-61878 The socio-economic and health impactsScope This British Standard provides a procedure for conversion which will give the essential accuracy required for precise dimensional interchangeability. The standard lays down an optimum fineness of rounding the converted size so that the conversion is made with the required precision and, at the same time, an excessive number of decimal places in the converted size is avoided. The procedure adopted is designed to ensure correct acceptance or
