20litre

Twenty litres, denoted 20 L, is a unit of volume in the metric system. One litre is defined as one cubic decimeter, so 20 litres equal 20 dm^3, which is 0.02 cubic metres or 20,000 cubic centimetres. In US customary units, 20 litres is about 5.28 US gallons; in imperial terms it is about 4.41 imperial gallons.

Common uses for a 20-litre quantity include measuring liquids for cooking, beverages, and industrial applications. It is a standard carrying capacity for various containers, such as water jerry cans, paint buckets, and bulk liquid drums. The 20-litre drum is a widely used packaging size for paints, solvents, and other liquids in many regions, offering a balance between manageable weight and sufficient volume.

In writing and measurement practice, the term is usually spelled “litre” in British English and “liter” in American English. The official symbol for the unit is the capital letter L. The lowercase l is sometimes used but can be confused with the digit 1, so the preferred form is L in technical contexts.

Notes: If encountered as a product name or label, “20litre” may refer to containers or packaging designed to hold twenty litres, but it is not a separate unit of measurement. As a concept, 20 litres denotes a specific volume and can be converted to other units as needed.
