升

定义
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)等于 1 000 cubic centimeters (1 000 cm³) or 0.001 cubic meters (0.001 m³).

起源
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.

现代使用
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.

毫升

定义
A milliliter (symbol: mL) is one-thousandth of a liter, equal to 1 立方厘米（1 立方厘米） or 1 × 10⁻⁶ cubic meters (1 × 10⁻⁶ m³).

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

现代使用
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.
