The US pint (pt) is an imperial volume unit equal to one-eighth of a US gallon or approximately 0.4732 liters, best known for sizing beer glasses and ice cream containers in America. The phrase 'a pint is a pound the world around' captures its colloquial significance, though a pint of water actually weighs about 1.043 pounds. One US pint equals exactly 16 US fluid ounces.

The teaspoon (tsp) is the smallest standard cooking volume unit, equal to approximately 4.929 milliliters, found in recipes worldwide for measuring small quantities of spices, extracts, and medicine. It serves as the building block for larger measurements, with three teaspoons making one tablespoon. One US teaspoon equals exactly 1/6 of a US fluid ounce.
