About these units
Exaliter (EL)
An exaliter, equal to 10¹⁸ liters, appears in discussions of planetary-scale volumes, such as estimating water content across extraterrestrial oceans, atmospheric volumes of gas giants, or hydrospheric mass estimates in exoplanet research. Because this unit is so large, it is rarely used in practical Earth-based science except in global summations. However, in cosmology or exoplanet studies, Vast quantities of liquids or gases on super-Earths or ocean worlds may be expressed in EL to maintain manageable numeric magnitudes. The exaliter represents the outer limits of volumetric units still grounded in physical application rather than purely abstract scaling.
Gallon (UK) (gal (UK))
The UK gallon, defined as 4.54609 liters, is larger than the US gallon by nearly 20%. It originated from the British desire to standardize wine and ale measures, leading to a uniform definition during the 19th century. Today, the UK gallon appears in older recipes, fuel consumption discussions, and British Commonwealth trade documents. Although the UK now uses liters for petrol and milk, the gallon remains culturally familiar, especially in automotive contexts such as miles per gallon (MPG), where both imperial and US definitions cause frequent confusion. The UK gallon's legacy persists through its continued use in some Commonwealth nations and specialized industries where imperial measures remain customary.
