Discusses the origins of our present-day measuring systems, how people measured lengths in the past, the different systems and how to convert from one to another, and examples of unusual lengths.

Presents activities involving quantity, proportion, length and weight, estimating and approximating with numbers, and graphic representation.

First completely interactive, computer-based, self-paced calculus courseware. Contains 4 books. Casebound. Paper.

This should be of interest to researchers in universities, research centres and industries who are involved in measurements and need advanced mathematical tools to solve their problems, and to whoever is working in the development of these mathematical tools. Advances in metrology depend on improvement in scientific and technical knowledge and in instrumentation quality as well as a better use of advanced mathematical tools and in the development of new ones. In this book, scientists from both the mathematical and the metrological fields exchange their experiences. Industrial sectors such as instrumentation and software, are likely to benefit from this exchange, since metrology has a high impact on the overall quality of industrial products and applied mathematics is becoming more and more important in industrial processes.

This is a maths textbook for the younger reader that considers capacity. Very simple text promotes discussion about the illustrations and encourages further investigation. The book also includes notes for teachers and parents.
