(v) 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 Btu's;

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.

nominations span one day only). Intra-day nominations do not

replace the remainder of a standing nomination. There is no

need to re-nominate if intra-day nomination modifies existing



(vii) An intra-day nomination is a nomination submitted

after the nomination deadline whose effective time is no

earlier than the beginning of the gas day and runs through

the end of that gas day.
