Metric regions commonly use the tonne of oil equivalent (toe), or more often million toe (Mtoe). 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).
In the oil industry, quantities of crude oil are often measured in metric tons. One can calculate the approximate number of barrels per metric ton for a given crude oil based on its API gravity: barrels of crude oil per metric ton = API gravity + 131.5 141.5 × 0.159 {\displaystyle {\text{barrels of crude oil per metric ton}}={\frac {{\text{API ...
1 is a required parameter, which specifies the number of oil barrels to be converted to tonnes (metric tons). Please do not format this parameter; i.e., use 1234 instead of 1,234. API is the API gravity factor. The default value is 33.4, corresponding to a density of 858.1 kg/m³ or 7.330 bbl/t at 60 °F. 2 can either be a word or a number ...
One common term is barrels per day (BPD, BOPD, bbl/d, bpd, bd, or b/d), where 1 BPD is equivalent to 0.0292 gallons per minute. [13] One BPD also becomes 49.8 tonnes per year. [ 13 ] At an oil refinery, production is sometimes reported as barrels per calendar day (b/cd or bcd), which is total production in a year divided by the days in that year.
For other isotopes, the isotopic mass is usually within 0.1 u of the mass number. For example, 35 Cl (17 protons and 18 neutrons) has a mass number of 35 and an isotopic mass of 34.96885. [7] The difference of the actual isotopic mass minus the mass number of an atom is known as the mass excess, [8] which for 35 Cl is –0.03115.
The problem may be solved using simple addition. With 64 squares on a chessboard, if the number of grains doubles on successive squares, then the sum of grains on all 64 squares is: 1 + 2 + 4 + 8 + ... and so forth for the 64 squares. The total number of grains can be shown to be 2 64 −1 or 18,446,744,073,709,551,615 (eighteen quintillion ...
A long ton, also called the weight ton (W/T), [1] imperial ton, or displacement ton, is equal to: 2,240 pounds (1,016.0 kilograms; 1.0160 metric tons) exactly 12% more than the 2,000 pounds of the North American short ton , being 20 long hundredweight (112 lb) rather than 20 short hundredweight (100 lb)
Builder's Old Measurement (BOM, bm, OM, and o.m.) is the method used in England from approximately 1650 to 1849 for calculating the cargo capacity of a ship. It is a volumetric measurement of cubic capacity. It estimated the tonnage of a ship based on length and maximum beam. It is expressed in "tons burden " (Early Modern English: burthen ...
