Units explained
Cubic Centimeter
A cubic centimeter is the volume of a cube one centimeter on a side, exactly equal to one milliliter.
Derived from the centimeter; long used in the centimeter–gram–second (CGS) system.
Standard for engine displacement, laboratory volumes and medical dosing (often written cc).
CGS system, 19th c.
US Teaspoon
A US teaspoon is one third of a US tablespoon (4.9289 mL).
A standardized small cooking measure.
Used everywhere in US recipes and home dosing.
US cooking measure.
