Units explained
Cubic Foot
A cubic foot is the volume of a cube one foot on a side (28.3168 L).
Derived by cubing the international foot (0.3048 m).
Used for natural gas, refrigerators, shipping and HVAC.
1959 yard agreement.
Drop
A drop is a nominal small volume of about 0.05 mL; the exact size varies with the liquid and dropper.
Standardized loosely in pharmacy as roughly 1/20 of a milliliter (the metric drop).
Used for liquid medication and flavor dosing; treat as approximate.
Pharmacy convention.
