It is not strictly a conversion as the heat content of natural gas varies with the chemical composition. It is mostly methane, but the traces of propane, butane, and other gases affect heat content. Using a DoE typical figure of 1089 BTU/ft and converting, it is about 40.5 MJ/m

As 1 kWh = 3.6 MJ, this is about 11.3 kWh per cubic meter.

Red face convert from hcf to kilowatt hour

thank you for your fast answer!!

by the way, are you aware about a conversion, for gas again, between the hcf (I don't know what it is, I suppose it is Hundred Cubic Feet, but it seems strange to measure gas, normally it's to measure liquid such as water, it normally corresponds to 748 gallons), so between hcf and kWh.
someone told that the conversion factor was about 1.022640 but I don't know if it's true, nor how I can use it...

please help me again.... thank you

Using the same 1089 BTU/ft figure as above, that is 1.149 MJ/ft or 114.9 MJ/CCF (We use CCF for hundred cubic feet here). Converting both to kWh (3.6 MJ/kWh), that is 0.319 kWh/ft or 31.9 kWh/CCF.

No, because one is flow and the other volume.

A one cubic meter tank of water will just sit there, with no flow at all. If there is a hole in the tank, it will flow over some period of time (hard to solve for) and soon you won't have a cubic meter of water any more.

A cubic meter of water is about 264.2 (US) gallons. You can convert one volume unit to another.
