The unit of volume usually used for natural gas is the standard cubic meter (Nm), not the actual cubic meter (m). Standard cubic meter refers to the gas volume at a temperature of 20℃ and a pressure of 1 atm.

The conversion relationship between the bidder and the actual party is as follows:

1 standard cubic meter (nautical mile) = 1000 liter

1 standard cubic meter (nautical mile) = 0.00 1 cubic meter

1 m3 (m) = 1000 standard m3 (nautical mile)

For example, a natural gas pipeline transports 100 cubic meters of natural gas per hour, so its standard cubic meter flow is:

100 USD \ multiplied by 1000 = 100000 standard cubic meter/hour USD.

Note that when calculating the natural gas flow, it is necessary to convert the actual volume into the standard volume.
