Barrel of oil equivalent 10 BTU equals 6.1178632 × 10 J, about 6.1 GJ (HHV), or .) The value is necessarily approximate as various grades of oil and gas have slightly different heating values. If one considers the lower heating value instead of the higher heating value, the value for one BOE would be approximately 5.4 GJ (see ton of oil equivalent). Typically or 58 CCF are equivalent to one BOE. The USGS gives a figure of 6,000 cubic feet (170 cubic meters) of typical natural gas. A commonly used multiple of the BOE is the kilo barrel of oil equivalent (kboe or kBOE),
