About these units
Liter (L, l)
The liter is one of the most widely used units of volume worldwide, defined as the volume of a cube measuring 10 centimeters on each side, making 1 L = 1,000 cubic centimeters = 1 cubic decimeter. Despite not being an SI base unit, it is fully accepted for use with the SI system due to its universal practicality. The liter occupies a sweet spot: large enough to measure beverages, fuel, and household liquids, yet small enough for precise laboratory use. Its intuitive scale simplifies everyday tasks—recipes, medical dosages, aquarium capacities, and fuel economy are all naturally expressed in liters. In science, the liter's alignment with the metric system makes it indispensable for expressing fluid volumes, solution concentrations (L in mol/L), and gas quantities under standard conditions. Industrial systems use liters for chemical processing, water treatment, and food production, making it a cornerstone of modern volume measurement.
Cup (UK) (cup (UK))
A UK cup equals 284 mL, slightly larger than both the US cup and the metric cup. Used historically in British cooking, the UK cup is now largely superseded by grams and milliliters, but it remains relevant when interpreting older recipe books and culinary traditions. Its intermediate size provided a convenient measure in a pre-metric world and still appears in baking communities that prefer imperial standards.
