CDP Technical Note: Conversion of fuel data to MWh

you need to convert the volume of the fuel into a mass – or have the NCV expressed in terms of volume. Usually, a step will be required to convert mass into volume and this is done by using a conversion parameter known as density that expresses the mass per a unit of volume (e.g. kg/m3). You can find some density values in Table 2, below.
