OIL INDUSTRY CONVERSIONS |
|
Crude petroleum, and the refined products made from crude oil, are
normally measured either by volume in gallons and US barrels, or by weight
in tons or tonnes. The relationship between volume and weight is usually
measured by density in the United Kingdom (the alternative measure is
relative density or specific gravity). American oilmen usually reckon
quantities of oil produced, moved or processed in barrels per day (bpd
or b/d). The loose but simple rule of thumb for conversion is that a barrel
a day is roughly 50 tonnes a year, but the relationship varies according
to density and so according to product.

For example:
1 Barrel (BBL) of petroleum or related products = 42 gallons
1 Barrel (BBL) Thousand cubicmeters (TCM) 0.0001590
1 Barrel (BBL) 0.1364 metric tons (MT)
1 Gallon = 124,000 Btu (rounded to nearest 1000)

USING BRITISH THERMAL UNITS (BTU) TO COMPARE ENERGY
Physical units reflect measures of distances, areas, volumes, heights, weights,
mass, force, impulse and energy. Different types of energy are measured by different
physical units: barrels or gallons for petroleum; cubic feet for natural gas;
tons for coal; kilowatt-hours for electricity. To compare different fuels, we
need to convert the measurements to the same units.
The quantity of heat required to raise the temperature of one pound of water by one degree Fahrenheit at or near 39.2° Fahrenheit.
Some popular units for comparing energy include: British Thermal Units (Btu), barrels of oil equivalents, metric tons of oil equivalents, metric tons of coal equivalents, and terajoules.
In the United States, the British Thermal
Unit (Btu), a measure of heat energy, is the
most commonly used unit for comparing fuels. Because energy used in different countries comes from different places, the Btu content of fuels varies slightly from country to country. The Btu content provided below and used in the energy calculator reflect the average energy contents for fuels consumed in the United States.
BTU Content of Common Energy Units
1 barrel (42 gallons) of crude oil = 5,800,000 Btu
1 gallon of gasoline = 124,000 Btu
1 gallon of diesel fuel = 139,000 Btu
1 gallon of heating oil = 139,000 Btu
1 barrel of residual fuel oil = 6,287,000 Btu
1 cubic foot of natural gas = 1,031 Btu
1 gallon of propane = 91,000 Btu
1 short ton of coal = 20,754,000 Btu
1 kilowatthour of electricity = 3,412 Btu
