(a) Btu - The term "Btu" ("British thermal unit") shall mean

the amount of heat required to raise the temperature of

degrees Fahrenheit. The standard Btu is the

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

day shall be the date of the beginning of such day.


(e) Dekatherm - The term dekatherm (Dth) shall mean the

quantity of heat energy which is equivalent to 1,000,000

Btu. One "dekatherm" of gas shall mean the quantity of

gas which contains one dekatherm of heat energy. The

standard quantity for measurement, nominations,

confirmations, scheduling, allocations, and billing shall

be dekatherms per gas day in the United States. The

standard for Canada shall be Gigajoules per gas day.

(For reference 1 dekatherm = 1,000,000 Btu's; and 1

gigajoule = 1,000,000,000 joules.) For commercial

purposes, the standard conversion factor between

dekatherms and gigajoules is 1.055056 gigajoules 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.
