Proposed change

Complementary to home-assistant/home-assistant.io#40281 and home-assistant/core#150015, this documents MCF as another alternative volume unit, as this is how some utilities in the US bill for water or gas.

Type of change

  • Document existing features within Home Assistant
  • Document new or changing features for which there is an existing pull request elsewhere
  • Spelling or grammatical corrections, or rewording for improved clarity
  • Changes to the backend of this documentation
  • Remove stale or deprecated documentation

Checklist

  • I have read and followed the documentation guidelines.
  • I have verified that my changes render correctly in the documentation.

53-53: MCF addition looks correct; consider clarifying the abbreviation once.

The unit list now contains MCF, which is great. Because M can ambiguously stand for thousand or million in different domains, a one-time footnote or short parenthetical “(thousand ft³)” elsewhere in the doc would pre-empt confusion.

53-53: Clarify that MCF = thousand cubic feet

Add a short clarification to avoid ambiguity with “million cubic feet” used elsewhere.

-| `NumberDeviceClass.GAS` | L, m³, ft³, CCF, MCF | Volume of gas. Gas consumption measured as energy in kWh instead of a volume should be classified as energy.
+| `NumberDeviceClass.GAS` | L, m³, ft³, CCF, MCF | Volume of gas. Gas consumption measured as energy in kWh instead of a volume should be classified as energy. “MCF” denotes thousand cubic feet.

82-82: Grammar: “represent consumption”

Tighten phrasing.

-| `NumberDeviceClass.VOLUME` | L, mL, gal, fl. oz., m³, ft³, CCF, MCF | Generic volume, this device class should be used to represent a consumption, for example the amount of fuel consumed by a vehicle.
+| `NumberDeviceClass.VOLUME` | L, mL, gal, fl. oz., m³, ft³, CCF, MCF | Generic volume, this device class should be used to represent consumption, for example the amount of fuel consumed by a vehicle.
docs/core/entity/sensor.md (2)

56-56: Clarify that MCF = thousand cubic feet

Mirror the clarification here as well for consistency with number.md.

-| `SensorDeviceClass.GAS` | L, m³, ft³, CCF, MCF | Volume of gas. Gas consumption measured as energy in kWh instead of a volume should be classified as energy.
+| `SensorDeviceClass.GAS` | L, m³, ft³, CCF, MCF | Volume of gas. Gas consumption measured as energy in kWh instead of a volume should be classified as energy. “MCF” denotes thousand cubic feet.

86-86: Grammar: “representing consumption”

Minor style tweak.

-| `SensorDeviceClass.VOLUME` | L, mL, gal, fl. oz., m³, ft³, CCF, MCF | Generic volume, this device class should be used for sensors representing a consumption, for example the amount of fuel consumed by a vehicle.
+| `SensorDeviceClass.VOLUME` | L, mL, gal, fl. oz., m³, ft³, CCF, MCF | Generic volume, this device class should be used for sensors representing consumption, for example the amount of fuel consumed by a vehicle.

53-53: Add MCF to GAS — LGTM

Consistent with other docs and unit style.


82-82: Add MCF to VOLUME — LGTM


84-84: Add MCF to VOLUME_STORAGE — LGTM


85-85: Add MCF to WATER — LGTM


53-85: Avoid doc drift: confirm core + conversion support for MCF

Ensure the linked core PR (#150015) adds MCF to unit constants, conversion/normalization, and any unit system mappings so statistics and UI behave correctly.

86-89: Check statistics normalization for MCF

Please confirm Recorder/Statistics normalization includes MCF for GAS/VOLUME/WATER to allow mixed-unit charts and consistent long-term stats.
