Interconversion of Units
This chapter reviews the simple interconversion of measurement units between systems that is facilitated by available linear conversion factor tables. It discusses the background for application of dimensional analysis to help ensure a dimensionally consistent final result from complex conversions, but also notes why dimensional consistency will not always ensure you end up with the correct units or values. The use of the “Factor-Label” approach to conversion is discussed as one way to reduce the chance of error in conversions involving multiple units and factors and to reduce the risk of missing a factor. The handful of interconversions which require non-linear approaches, such as converting degrees Baumé to specific gravity, are highlighted along with a few other conversion exceptions.
