About these units
Milliliter (mL)
A milliliter, defined as 1/1,000 of a liter or precisely 1 cubic centimeter, is a small but enormously significant volume unit in cooking, medicine, pharmacy, and laboratory science. Medical syringes, dosing spoons, and IV solutions rely heavily on milliliter accuracy. In laboratories, mL measurements are routine for preparing reagents, dilutions, and biological media. Because 1 mL = 1 cm³, many devices use either notation interchangeably depending on context. Despite its small size, the milliliter is commonly used in daily life as well—perfume bottles, beverage labels, and household cleaners often list contents in milliliters. Its precision and simplicity make the milliliter one of the world's most practical measurement units.
Attoliter (aL)
An attoliter is a staggering 10⁻¹⁸ liters, placing it firmly in the realm of molecular and nanoscale science. This unimaginably small volume corresponds to spaces comparable to the inside of viruses, nanopores, or clusters of biomolecules. Cutting-edge technologies like nano-droplet reactors, atomic force microscopy, and high-precision spectroscopy rely on attoliters to describe reaction chambers or sample sizes. The attoliter is so small that even a single bacterial cell has a volume approximately one million attoliters. This makes the unit essential for exploring the physical limits of chemical reactions and biological processes.
