Does the system switch Number:Temperature between imperial/metric in all bindings?

For OH2.5 I got the data into Grafana for charting and gauges without using a binding. I still would like a binding to reduce the coding.

I enabled the local API option for the Awair using the app and then in openHAB setup HTTP caching and regex to extract the needed data.

eg cache http://192.168.1.6/air-data/latest
