About these units
Picoliter (pL)
A picoliter is 10⁻¹² liters, bridging the gap between femtoliters and nanoliters. Many biological cells—such as yeast—have volumes in the picoliter range. This makes the unit particularly important in cell biology, single-cell genomics, and droplet microfluidics. Inkjet printers famously eject droplets on the order of a few picoliters, illustrating a precise and widespread technological use. This droplet size affects print resolution, color quality, and material deposition accuracy. The picoliter is also used in chemical analysis, micro-sampling, and lab-on-chip devices, where controlling tiny fluid quantities is essential for efficiency and precision.
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.
