Re: [weewx-user] Problem with Unit Conversion

Thanks. It is sounding like my best, if not only, option is to trash the current database and to start over after modifying my service to record snow depth in inches and change the. usUnits to US. Fortunately this is a very new service and we have had zero snow. Unfortunately I am not able to

Re: [weewx-user] Problem with Unit Conversion

The data is in a separate dB as snow_depth. It is measured and archived in mm. The usUnits in each record is METRIC. If I am not mistaken, weewx has no idea how to convert snow_depth to anything else. Hence, if I am not mistaken, I will either need to convert the data before graphs are

[weewx-user] Problem with Unit Conversion

The new service I added saves snow depth measurements to its own sqlite database in archive format with measurements in mm. However, so far (since yesterday) the field usUnits has been posted as weewx.METRIC. I suspect that it should be set to weewx.METRICWX. 1) does it really matter what the
