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.
Petaliter (PL)
A petaliter represents 10¹⁵ liters, a massive unit used to quantify the total water content of oceans, polar ice sheets, or planetary atmospheres. Oceanographers may describe the Pacific Ocean's volume or the total ice volume of Antarctica in petaliters; these scales cannot be expressed meaningfully in smaller units without imposing huge, impractical numbers. The PL is also sometimes used in astronomy to approximate ocean-like features on other worlds, such as subsurface oceans on Europa or Enceladus. It represents one of the largest practical volumetric units before entering pure theoretical measurement.
