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?
