55liter

55 liters, denoted 55 L, is a unit of volume in the metric system. It equals 55 cubic decimeters (dm3), which is 0.055 cubic meters (m3) and 55,000 cubic centimeters (cm3). The liter is an accepted non-SI unit defined as the volume of a cube 10 cm on each side, so 1 L = 1 dm3. Since 1 m3 equals 1000 L, 55 L equals 0.055 m3.

Conversions to other measures include approximately 14.5 US gallons (55 L × 0.264172052), and about 12.1 imperial gallons (UK gallon = 4.54609 L). In milliliters, 55 L equals 55,000 mL.

55 liters is commonly used to describe capacities of liquids and containers. It appears in contexts such as beverage packaging, storage tanks, and the capacities of some refrigerators and camping gear. A 55 L backpack is a standard size for expedition or trekking use, though actual pack shapes and volumes vary.

Name and notation: the unit is named liter (British English litre) and is abbreviated with the symbol L. The uppercase L is preferred in many style guides to avoid confusion with the numeral 1 or the lowercase letter l. The liter is not an SI base unit but is accepted for use with the SI and is defined as the volume of a cubic decimeter.
