Oil traders, Houston, 2009 Nominal price of oil from 1861 to 2020 from Our World in Data. The price of oil, or the oil price, generally refers to the spot price of a barrel (159 litres) of benchmark crude oil—a reference price for buyers and sellers of crude oil such as West Texas Intermediate (WTI), Brent Crude, Dubai Crude, OPEC Reference Basket, Tapis crude, Bonny Light, Urals oil ...
This makes the measure important for market analysts. The OPEC Basket, including a mix of light and heavy crude oil products, is heavier than both Brent crude oil, and West Texas Intermediate crude oil. Since January 1, 2017, the OPEC reference basket consists of a weighted average of the following crudes: [1] Saharan Blend (from Algeria)
In Egypt, the monetary oka weighted 1.23536 kg. In Tripolitania, it weighed 1.2208 kg, equal to 2½ artals. The oka was also used as a unit of volume. In Wallachia, it was 1.283 liters of liquid and 1.537 L of grain (dry measure). In Greece, an oka of oil was 1.280 kg, which would have translated to about 1.340 litres (at 0.916 kg/l).
An overview of ranges of mass. To help compare different orders of magnitude, the following lists describe various mass levels between 10 −67 kg and 10 52 kg. The least massive thing listed here is a graviton, and the most massive thing is the observable universe.
Liquid water has a density of about 1 kg/dm 3, making any of these SI units numerically convenient to use as most solids and liquids have densities between 0.1 and 20 kg/dm 3. kilogram per cubic decimetre (kg/dm 3) gram per cubic centimetre (g/cm 3) 1 g/cm 3 = 1000 kg/m 3; megagram (metric ton) per cubic metre (Mg/m 3)
It is equal to 10 candareens and is 1 ⁄ 10 of a tael or approximately 3.78 grams. A troy mace is approximately 3.7429 grams. In Hong Kong, one mace is 3.779 936 375 grams. [2] and in Ordinance 22 of 1884, it is 2 ⁄ 15 ounces avoirdupois. In Singapore, one mace (referred to as chee) is 3.779 94 grams. [4]
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).
The pound or pound-mass is a unit of mass used in both the British imperial and United States customary systems of measurement.Various definitions have been used; the most common today is the international avoirdupois pound, which is legally defined as exactly 0.453 592 37 kilograms, and which is divided into 16 avoirdupois ounces.
