About Teaspoon (tsp)

A US culinary unit of volume equal to 1/3 of a tablespoon (about 4.93 mL). Teaspoons are the smallest everyday kitchen measurement — used for salt, spices, extracts, baking powder, and pharmaceutical liquid dosing. The "5 mL teaspoon" used in medicine is a rounded form of this unit. Tsp is also the standard unit in US baking recipes for yeast, leaveners, and flavorings where precision matters more than for liquid volumes.

About Milliliter (mL)

A metric unit of volume equal to one thousandth of a liter (0.001 L) or exactly one cubic centimeter. Milliliters are the everyday metric unit for medicine dosing, cooking measurements outside the US, laboratory chemistry, perfume and beverage cans. A standard medical syringe is 10 mL; a shot glass is about 44 mL; a standard intravenous saline bag is 500 or 1,000 mL. In chemistry and pharmacy, mL and cc (cubic centimeters) are used interchangeably.
