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 Celsius.
Gigajoule (GJ) – a measure of energy used to express the heating value of
natural gas or of energy consumed. One GJ is equivalent to one billion J. An average
home uses about 120 GJ 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 (m3) – a unit of volume measurement commonly used
to express the amount of natural gas sold to consumers. The typical home uses
about 3,200 m3 of natural gas per year.
