Having read for the umpteenth time recently comments implying that there is no need to change the database units from US to Metric I thought it was time to give my pennyworth. IMHO there is every reason in the world to change the units if one is living in the rest of the world outside the US. When (not if) one has to look at the database to resolve an issue using sqlite3 or MySQL there is nothing worse than being faced with a load of data which is unrecognisable and means nothing since the units are such they are never seen during daily life. pressures of 30.xxxx mean nothing when daily pressures are in mbar and temperatures are meaningless when in farenheit and daily weather temperatures are in Celsius. IMHO if you live outside the US your database should be Metric or Metricwx so that the data becomes meaningful when viewed directly.
I agree that for the purposes of weewx this is not necessary as all conversions will happen automatically. One final thing which I have done to my MySQL database is to redefine the columns to limit the number of decimal places to 2 in most cases. This makes viewing with MySQL directly much much more readable and gets rid of the totally unnecessary additional decimal places with little (if any) effect on weewx. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
