I'm not exactly sure what you want to do, but take a look through the convenience functions at the bottom of weewx/units.py. It may be as simple as:
record_metric = weewx.units.to_METRICWX(record) But, if your goal is to emit JSON formatted output, be sure to look through the wiki article *Tags for series <https://github.com/weewx/weewx/wiki/Tags-for-series>*. WeeWX may be able to do what you want already!
