Glossary of Natural Gas Measurements
Joule (J) – a base metric measure of energy. One J is the equivalent of the energy required to raise the temperature of one gram of water by approximately one quarter of one degree Celcius. Gigajoule (GJ) – a measure used to express the energy value of natural gas or of energy consumed. One GJ is equivalent to one billion J. A typical home in Saskatchewan uses about 105 GJ of natural gas per year. Terajoule (TJ) – a unit of energy equivalent to 1,000 GJ. Petajoule (PJ) – a unit of energy equivalent to 1,000,000 GJ. Cubic metre (m 3 ) – a unit of volume measurement commonly used to express the amount of natural gas sold to consumers. The typical home in Saskatchewan uses about 2,800 m 3 of natural gas per year. Natural Gas Volume Equivalents at Normal Atmospheric Pressure • One GJ of natural gas would approximately fill an 11-foot by 11-foot by 8-foot room (approximately 1,000 cubic feet). • One TJ of natural gas would fill a typical professional hockey arena (approximately 1,000,000 cubic feet). • One PJ is enough natural gas to fill 17 sports stadiums the size of the Rogers Centre in Toronto (approximately 1,000,000,000 cubic feet).
