About these units
Teaspoon (Metric) (tsp (m))
The metric teaspoon is universally fixed at 5 mL, offering complete consistency across countries that use metric culinary measurements. This simplicity is a major advantage over historical teaspoon variations. In metric recipe writing—especially in Australia, New Zealand, and parts of Europe—teaspoons serve as standardized micro-measures that are easy to convert and scale. Its widespread adoption demonstrates the advantages of aligning traditional kitchen practices with the predictable structure of the metric system.
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.
