Change unit of measurement for only history graph

I want to graph the temperature of two sensors from OpenHardwareMonitor and one from a Zigbee sensor, but they show in different units (°F and °C).

I only want to change the two OpenHardwareMonitor sensors to Fahrenheit in the history graph view and not in the entity itself.

It is not only about changing a UoM, it is about a conversion as well, right?

Yep. Should have been more clear about that!

Long reply time!

You could create a template sensor for each then edit the UoM for just that sensor.

Then, of course, show your new template sensors on the graph.

Of course the simplest solution should have been obvious! Thanks for your help!
