Which of the following is equivalent to the abbreviation "tsp"?

The abbreviation "tsp" stands for "teaspoon," which is a common unit of measurement in cooking and pharmacology. It is used to quantify small volumes of liquid or powdered substances. Knowing this abbreviation is crucial for tasks such as measuring medication doses, where accurate dosage is vital to ensure patient safety and efficacy of the treatment.

The other abbreviations represent different quantities: a tablespoon is larger than a teaspoon, a cup represents a much greater volume than either, and milliliters are a metric unit, which can also measure volume but are not equivalent to a teaspoon. Understanding these distinctions helps in accurately converting measurements and administering appropriate doses in various contexts.
