How many milliliters are in 1 teaspoon?

One teaspoon is equivalent to approximately 5 milliliters. This measurement is commonly used in both cooking and medicinal dosing, making it a standard unit of volume in the healthcare and culinary fields. Understanding this equivalency is essential for pharmacy technicians when converting between different measurement systems, particularly when preparing medications that may be prescribed or dispensed in liquid form.

The value of 5 mL for 1 teaspoon is useful in various clinical settings as it aids in accurate dosing for both patients and compounds. Moreover, it contributes to ensuring that patients receive the correct amount of medication, which is critical for safety and efficacy.

In contrast, the other options do not represent the accepted conversion for a teaspoon to milliliters, making them less relevant for accurate dosage calculations in practice.
