The centiliter (cL) is a metric unit of volume equal to one-hundredth of a liter, commonly used in European countries for beverage and spirit bottle sizes. Wine and spirit labels in the EU frequently display volume in centiliters alongside milliliters. One centiliter equals exactly 10 milliliters or about 0.338 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.
