GENERAL TERMS AND CONDITIONS

----------------------------

(d) The standard quantity for nominations, confirmation and

scheduling is dekatherms per gas day in the United States, gigajoules

per gas day in Canada and gigacalories per gas day in Mexico. (For

reference, 1 dekatherm = 1,000,000 Btus; 1 gigajoule = 1,000,000,000

joules; and 1 gigacalorie = 1,000,000,000 calories.) For commercial

purposes, the standard conversion factor between dekatherms and

gigajoules is 1.055056 gigajoules per dekatherm and between dekatherms

and gigacalories is 0.251996 gigacalories per dekatherm. The standard

Btu is the International Btu, which is also called the Btu (IT); the

standard joule is the joule specified in the SI system of units. The

International Btu is specified for use in the gas measurement standards

of the American Gas Association, the American Petroleum Institute, the

Gas Processors Association and the American Society for Testing

Materials. For non-commercial purposes, these associations note that

the exact conversion factor is 1.05505585262 Gigajoules per Dekatherm.
