About these units
Deciliter (dL)
A deciliter, 1/10 of a liter, appears prominently in medical diagnostics—especially in blood testing. Many laboratory measurements use dL as the denominator, such as mg/dL for blood glucose or cholesterol levels. In Europe, food packaging sometimes lists nutritional values per deciliter, especially for dairy products and soups. The dL is just large enough to be meaningful while still small enough for dietary and medical precision. Though not as common as liters or milliliters, the deciliter serves specialized roles where moderate scale and medical tradition intersect.
Gigaliter (GL)
A gigaliter equals one billion liters or one million cubic meters. It is widely used when discussing very large natural or artificial water systems. Countries quantify national water reserves, lake capacities, and large-scale water transfers in gigaliters. For example, major reservoirs, such as those used for hydroelectric power generation, often have volumes in the tens of gigaliters. Environmental scientists use GL to describe groundwater extraction, rainfall totals across large regions, and freshwater availability. The GL helps quantify planetary-scale hydrological processes in a manageable numerical range.
