The preferred approach for handling such issues is to do the conversion in the code (presumably a WeeWX service) that adds the obs concerned to the loop packet or archive record. More specifically, if you have an obs whose units are/maybe different to other obs of the same type/group then you should check the usUnits field in the packet/record concerned and convert the obs value as necessary before adding the converted value to the packet/record. This way you maintain unit integrity of the packet/archive. Otherwise you risk some other service processing the mixed unit packet/record before your unit conversion occurs and resulting in incorrect output or worse still you may pollute your database.
I had a quick look and found this code <https://gitlab.com/wjcarpenter/bme280wx/-/blob/master/bin/user/bme280wx.py> that implements a WeeWX service to add BME280 data to WeeWX loop packets. Not saying this is a good or bad example, but if you have a look at the new_loop_packet() method you will see how the usUnits field can be used to check what unit system is being used in the packet and conversions can be done accordingly.
