About these units
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.
Fluid Ounce (UK) (fl oz (UK))
A UK fluid ounce equals 28.4130625 mL, slightly larger than the US fluid ounce. It forms part of the imperial system used in cooking, beverage preparation, and older pharmaceutical formulations. Imperial fluid ounces were historically derived from the UK gallon (1/160 of a gallon), distinguishing them from US units derived from a different gallon. Though metric units dominate in the UK today, fluid ounces still appear in bartending, antique recipes, and product packaging that caters to traditional preferences or legacy export markets.
