About these units
Cubic Foot (ft³)
A cubic foot equals 28.31684659 liters, representing the volume of a cube one foot on each side. It is widely used in construction, real estate, natural gas metering, and HVAC systems. Room ventilation rates, airflow in ducts, and gas consumption often use cubic feet or cubic feet per minute (CFM). Storage capacity for freezers, shipping containers, and building materials also frequently uses this unit. The cubic foot's relationship to the foot makes it practical in industries where imperial length units still dominate.
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.
