About these units
Ton Register (ton reg)
A register ton, or ton register, is a unit of volume, not mass, equal to 100 cubic feet. It is used in maritime contexts to measure the internal capacity of ships—specifically cargo-carrying volume, not weight. Ship registries rely on register tons to calculate taxes, port fees, and cargo classifications. The unit dates back to 19th-century maritime law, where consistent volumetric measurement was critical for international shipping regulation. Despite changes in global trade and containerization, register tons remain important for historical vessel documentation, as well as for understanding older merchant and naval ship specifications.
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.
