Non-system unit of natural gas volume: 

  1 GOE  = Gas Volume [Oil Equivalent]  / Gas Volume [True]

so that  V_{G, oil equiv} = 1 GOE  · V_{G, true}

The most widely used industry convention is 1 GOE = 0.001 so that:

• 1,000 m³ of gas is equivalent to 1 m³ of oil
  
• 1,000 ft³  is equivalent to 0.1781  bbl  of oil
• 5,615 ft³  is equivalent to 0.1781  bbl  of oil

The USGS convention is: 1 GOE = 0.000936 so that: 

• 1,000 m³ of gas is equivalent to 0.936 m³ of oil
• 1,000 ft³  is equivalent to 0.0001666  bbl  of oil
• 6,000 ft³  is equivalent to 1 bbl  of oil

The U.S. Internal Revenue Service convention is: 1 GOE = 0.0009684 so that:  

• 1,000 m³ of gas is equivalent to 0.9684 m³ of oil
• 1,000 ft³  is equivalent to 0.00017248 bbl  of oil
• 5,800 ft³  is equivalent to 1 bbl  of oil
