The official SI symbols are g/cm 3, g·cm −3, or g cm −3. It is equivalent to the units gram per millilitre (g/mL) and kilogram per litre (kg/L). The density of water is about 1 g/cm 3, since the gram was originally defined as the mass of one cubic centimetre of water at its maximum density at 4 °C (39 °F). [1]

Daily oil consumption by region from 1980 to 2006. This is a list of countries by oil consumption. [1] [2] In 2022, the International Energy Agency (IEA) announced that the total worldwide oil consumption would rise by 2% [3] year over year compared to 2021 despite the COVID-19 pandemic.

The kilogram per cubic metre (symbol: kg·m −3, or kg/m 3) is the unit of density in the International System of Units (SI). It is defined by dividing the SI unit of mass, the kilogram, by the SI unit of volume, the cubic metre. [1]
Heavy crude oil has an API gravity below 22.3° (i.e., 920 to 1000 kg/m 3) Extra heavy oil has an API gravity below 10.0° (i.e., greater than 1000 kg/m 3) However, not all parties use the same grading. [9] The United States Geological Survey uses slightly different ranges. [10] Crude oil with API gravity less than 10° is referred to as extra ...
For some usage examples, consider the conversion of 1 SCCM to kg/s of a gas of molecular weight , where is in kg/kmol. Furthermore, consider standard conditions of 101325 Pa and 273.15 K, and assume the gas is an ideal gas (i.e., Z n = 1 {\\displaystyle Z_{n}=1} ).

Used oil is considered the largest source of oil pollution in the U.S. harbors and waterways, at 1,460 ML (385 × 10 ^ 6 US gal) per year, mostly from improper disposal. [49] By far the greatest cause of motor-oil pollution in oceans comes from drains and urban street-runoff, much of it caused by improper disposal of engine oil. [ 50 ]
