Cubic meters (or another similar measure of volume) is what I’d expect. It’s the conversion to an unrelated and theoretical (since it’s not actually being converted to electricity) unit that confuses me. I presume it’s to make it easier to compare electric vs gas heat, but the variable efficiency of burning gas and the existence of heat pumps ruin that.
kWh is a unit of energy. Regardless of whether it is in the form of electricity or from burning fuel. So it is actually very related, and much more useful than a measurement of volume I’d argue. The measurement is of course done in m³, but then a conversion factor based on several factors is used to convert to an actually useful unit.
A m³ of gas really could be anything depending on pressure, temperature and constituents.
(Brace yourself for Much 'Merica) Several gas utilities I’ve had in the USA measure natural gas CCF, which is 100 cubic feet (at some standard temperature/pressure), which happens to be almost exactly the same as a Therm, or 100,000 BTU.
Very common in countries that use the metric system (ie literally everywhere except the USA). It’s measured either in kWh or in m^3

Yeah, even firewood can be (and not uncommonly is) measured in kWh
