[Digestion] daily avg volume of fuel for cooking - conversions?

[Björn Dahlroth]

For rough calculations it is practical to know that 1 NTP cubicmeter of
natural gas has a practical heat content (lower heating value) very close to
10 kWh. On your natural gas bill the volume of gas is mostprobably given at
NTP (normal temperature and pressure).

I'm curious if someone here could help me compare this figure with, for
instance, my average daily consumption of natural gas for cooking. I know
how to convert cubic feet to cubic meters, but have forgotten the different
energy densities and am unsure if pressure is an important parameter here. 

We average 11.4 cubic feet* per day of natural gas for our cooking needs.
Anyone care to weigh in on how this compares to 0.75 m3 of biomethane?

Thanks.

* I calculate 0.323m3 or about 40% of the 0.75m3 on a purely volumetric
basis.
