A multitude of measurement units exist within astronomy, some of which are unique to the subject, causing discrepancies that are particularly apparent when astronomers collaborate with other disciplines in science and engineering. The International System of Units (SI) is based on a set of seven fundamental units from which other units may be derived. However, many astronomers are reluctant to drop their old and familiar systems. This handbook demonstrates the ease with which transformations from old units to SI units may be made. Using worked examples, the author argues that astronomers would benefit greatly if the reporting of astronomical research and the sharing of data were standardized to. | Richard Dodd Using SI Units in Astronomy USING SI UNITS IN ASTRONOMY A multitude of measurement units exist within astronomy some of which are unique to the subject causing discrepancies that are particularly apparent when astronomers collaborate with other disciplines in science and engineering. The International System of Units SI is based on a set of seven fundamental units from which other units may be derived. However many astronomers are reluctant to drop their old and familiar systems. This handbook demonstrates the ease with which transformations from old units to SI units may be made. Using worked examples the author argues that astronomers would benefit greatly if the reporting of astronomical research and the sharing of data were standardized to SI units. Each chapter reviews a different SI base unit clarifying the connection between these units and those currently favoured by astronomers. This is an essential reference for all researchers in astronomy and astrophysics and will also appeal to advanced students. RICHARD DODD has spent much of his astronomical career in New Zealand including serving as Director of Carter Observatory Wellington and as an Honorary Lecturer in Physics at Victoria University of Wellington. Dr Dodd is Past President of the Royal Astronomical Society of New .
