Without knowing whether this is atmospheric-pressure natural gas, pipeline-pressure or compressed natural gas (and the pressure it's been compressed to), or liquefied natural gas, this is an unanswerable question.
You look up the density of natural gas, make sure it is expressed as kilograms (or tons) per cubic meter, convert it to those units if it isn't, and then multiply the volume by the density.
cubic meters x 61,023.74 = cubic inches
1Nm3=0.0098788
Cubic meters x 1 million = cubic centimeters
Convert cubic meters in kilograms? No can do. Cubic meters is a volume, kilos are weight. Unless you know the density you can't get an answer.
You can convert cubic feet to cubic meters, or feet to meters. But you can't convert cubic feet to meters.
You look up the density of natural gas, make sure it is expressed as kilograms (or tons) per cubic meter, convert it to those units if it isn't, and then multiply the volume by the density.
Multiply cubic meters by 1,000.
cubic meters x 61,023.74 = cubic inches
How to convert mmbtu to cubic meter
There is no direct conversion. Cubic meters is volume and square meters is area.
1Nm3=0.0098788
Cubic inches x 0.0000164 = cubic meters
Cubic meters cannot be converted into meters; cubic meters are units of volume and meters are units of length.
Cubic meters x 1 million = cubic centimeters
560 cubic feet are 15.857434092 cubic meters.
cubic meters x 1,000 = liters
