Describe the issue you are experiencing

When the energy dashboard converts a sensor to match the localization unit settings for HomeAssistant, the unit is not accurately shown on the energy graphs. It seems like HomeAssistant is doing the unit conversion, but maintains the original unit label on the UI. In my case, a gas meter MQTT sensor is collected in cubic meters, the dashboard converts it to cubic feet based on my localization settings, but the labels still show cubic meters.

Describe the behavior you expected

The units should report as cubic feet, or no conversion should happen.

Steps to reproduce the issue

1. Configure HomeAssistant for Imperial units.

2. Configure a sensor to collect gas consumption in cubic meters. Example:

   - platform: mqtt
   name: Gas Meter
   state_topic: "rtlamr/xxxxxxxxxx/state"
   device_class: gas
   state_class: total_increasing
   unit_of_measurement: "m³"

3. Add the gas sensor to the energy dashboard. See my sensor here that increased by 18 cubic meters over the hour:

4. Observe the the graphs display values converted to cubic feet, but the labels still show cubic meters.

I can confirm. My daily total right now is showing 16.5732 cubic meters but energy page is showing 566.8 cubic meters. If I convert to cubic feet then it pretty matches. Thus the numbers displayed are in cubic feet (baed on Imperial units) but the label still shows cub meters instead of cubic feet.

I am facing similar issue. I live in Europe sp the metric system in set in Home assistant. Gas usage shows around 10 times more then the actual true values. I dont make any conversions because the meter reading values are in m3 and also the summarized usage values are also in m3.

My settings for utility meter:

utility_meter: gas_usage_monthly: source: sensor.gas_meter cycle: monthly

This issue appears to be resolved now. The energy dashboard is now showing labels as cubic feet.
