 ### Energy Sector

• for coal and oil, the NCV is about 5 % less than the GCV • for most natural and manufactured gas, the NCV is about 10 % less o Where fuel characteristics (moisture, hydrogen and oxygen contents) are known, the 2006 IPCC Guidelines give a more precise method to convert GCV to NCV data: NCV = GCV − − − ### Fuels

The given values are for fuels with the given density. The variation in quality may give heating values within a range 5 10% higher and lower than the given value. Also the solid fuels will have a similar quality variation for the different classes of fuel. 1 Btu (IT)/lb = MJ/t = J/kg = kcal/kg = kWh/kg. ### converting arb values to adb
