Natural Gas Parameters Expressed in Volume

The trade of natural gas commonly in its liquefied form (LNG) is usually expressed in units of mass such as BTU/lb or traded in $/BTU units specially in the North American Region. However upcoming trends require that natural gas or LNG be traded in compliance to ISO 13686 Requirements, i.e, expressed in Volume (m3) rather than mass (lb), e.g., the EU and Asian Region.
