About these units
Drop (drop)
The drop is one of the oldest fluid measures and originally referred simply to the amount of liquid that naturally forms at the end of a dripping vessel. Because drop size depends on viscosity, surface tension, temperature, and orifice size, early medicine found drops inconsistent and unreliable. Modern medicine and chemistry sometimes define a drop as 0.05 mL, but this is only a convention used for standardized droppers—real drops can vary significantly. Despite its imprecision, the drop survives in everyday language, aromatherapy, essential oils, and household instructions ("add a few drops"). It exemplifies humanity's earliest attempts to quantify small volumes before scientific instrumentation enabled precise micro-measurement.
Stere (st (vol))
A stere is exactly 1 cubic meter, but with a particular association: it was defined specifically for measuring stacked firewood. Logs are irregular, so the stere measures the approximate space that a cubic meter of stacked wood occupies (including air gaps). The stere is still used in France and some other European regions as part of forestry traditions. Firewood sales often use the stere to maintain consistency with historical practices. The stere's survival shows how volume measurement often reflects cultural and economic tradition rather than purely scientific convenience, especially in long-standing industries like wood harvesting.
