Measurements, Calculations and Units of Sale

Since the last edition of this book was published, two most significant changes have taken place in the trade under the heading of this chapter. In the UK decimal currency has been introduced and, with few exceptions, which will be mentioned later, the trade has changed from Imperial to metric measure. Despite opposition from some quarters, this was a logical change, because at least 85 per cent of the world’s population operates under a metric system and 75 per cent of the world’s trade is transacted in metric terms. There is no doubt that world metrication will be achieved in due course.
