    This definition ultimately became the statement that 1 IT calorie is exactly 4.1868 J. [4] [8] The Btu is then calculated from the calorie as is done for the thermochemical definitions of the BTU and the calorie, as in International standard ISO 31-4 Quantities and units—Part 4: Heat and British Standard BS 350:Part 1:1974 Conversion factors ...

  3. Barrel of oil equivalent - Wikipedia

    en.wikipedia.org/wiki/Barrel_of_oil_equivalent

    Since this is a measurement of mass, any conversion to barrels of oil equivalent depends on the density of the oil in question, as well as the energy content. Typically 1 tonne of oil has a volume of 1.08 to 1.19 cubic metres (6.8 to 7.5 bbl).

    A decatherm or dekatherm [5] (dth or Dth) is 10 therms, which is 1,000,000 British thermal units or 1.055 GJ. [6] [7] It is a combination of the prefix for 10 (deca, often with the US spelling "deka") and the energy unit therm.

  6. Gasoline gallon equivalent - Wikipedia

    en.wikipedia.org/wiki/Gasoline_gallon_equivalent

    The fuel consumption is an equivalent measure for cars sold outside the United States, typically measured in litres per 100 km traveled; in general, the fuel consumption and miles per gallon would be reciprocals with appropriate conversion factors, but because different countries use different driving cycles to measure fuel consumption, fuel ...

  8. Tonne of oil equivalent - Wikipedia

    en.wikipedia.org/wiki/Tonne_of_oil_equivalent

    The tonne of oil equivalent (toe) is a unit of energy defined as the amount of energy released by burning one tonne of crude oil.It is approximately 42 gigajoules or 11.630 megawatt-hours, although as different crude oils have different calorific values, the exact value is defined by convention; several slightly different definitions exist.

  9. Million standard cubic feet per day - Wikipedia

    en.wikipedia.org/wiki/Million_standard_cubic...

    Million standard cubic feet per day is a unit of measurement for gases that is predominantly used in the United States.It is frequently abbreviated MMSCFD. MMSCFD is commonly used as a measure of natural gas, liquefied petroleum gas, compressed natural gas and other gases that are extracted, processed or transported in large quantities.
