About these 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.
Teaspoon (UK) (tsp (UK))
The UK teaspoon is defined as 5 milliliters, a value adopted in modern culinary and medical standards. Historically, however, its size varied considerably, often ranging from 4 to 6 mL depending on household spoons, region, or era. The modern 5 mL standardization brought consistency to recipes, pharmaceutical dosing instructions, and food labeling. Because teaspoons were once everyday household items rather than calibrated instruments, the move toward fixed metric equivalents significantly improved recipe reliability and medical accuracy. Despite the shift to SI units, the teaspoon endures as a culturally intuitive volume measure used in cooking and oral medication dosing, tying contemporary practice to long-standing domestic traditions.
