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.
Dram (dr)
The fluid dram is a small historical unit equal to 1/8 of a US fluid ounce or 3.6967 mL (US), with slightly different imperial values. It originated in apothecaries and early pharmaceutical texts, where drams measured potent liquid medicines, tinctures, and extracts. In daily life, drams appeared in old cocktail recipes, medicinal syrups, and household remedies. However, the inconsistency between US and UK drams, along with the rise of the metric system, pushed it out of modern use. Today, the dram survives mostly in whiskey culture—where a "dram" informally means a small pour, not a precise measurement—and in historical studies of medicine.
