Liter

Definition
A liter (symbol: L) is a commonly used volume measure in the metric world. Technically not an SI base unit, it’s defined as 1 cubic decimeter (1 dm³), which equals 1 000 cubic centimeters (1 000 cm³) or 0.001 cubic meters (0.001 m³).

Origins
From 1901 to 1964, the litre was tied to the mass of one kilogram of pure water at its densest point. Variations in water’s temperature, pressure, purity, and the slight mismatch in the kilogram prototype led to a return to the simpler definition: exactly one cubic decimeter.

Modern Use
Liters label beverage bottles, milk jugs, and fuel pumps worldwide. They also describe trunk volume in cars, pack capacities, appliance interiors, and recycling bin sizes—virtually any application where medium-sized volumes matter.

Milliliter

Definition
A milliliter (symbol: mL) is one-thousandth of a liter, equal to 1 cubic centimeter (1 cm³) or 1 × 10⁻⁶ cubic meters (1 × 10⁻⁶ m³).

Origins
As a submultiple of the liter—originally the French litre, derived from litron—the milliliter follows directly from the metric prefix “milli-,” meaning one-thousandth.

Modern Use
Milliliters measure small quantities: medicine doses, lab solutions, travel-size toiletries, condiment packets, and more. Precision instruments like pipettes, graduated cylinders, and measuring spoons rely on mL graduations.
