In my software project, all measurements exist as engineering units since they all come from various systems (ADCs or DSP boxes). We pass the values around to other pieces of software but are displayed as both the original values and converted units. We have a config file that contains both units and conversion polynomials, ranging from linear to cubic polynomials. Some of the DSP-derived values are at best an approximation so these have special flags that basically mean "for reference only". Having the unit is helpful for these but are effectively meaningless since the numbers are not precise enough, it would be like trying to determine lumens of a desk lamp from a photo taken outside of a building with the shades drawn.
