How many milliliters are equivalent to one teaspoon?

One teaspoon is equivalent to 5 milliliters. This measurement is commonly used in both cooking and pharmacology for dosing. Knowing this conversion is essential for pharmacy technicians, as they often need to accurately convert between different units of measurement when preparing medications.

The conversion from teaspoons to milliliters is based on standardized measurements established for consistency in dosing. This is particularly relevant when calculating dosages for liquid medications. Additionally, being familiar with these conversions can help prevent medication errors that could arise from using incorrect dosages.

While other options represent different measurements for various substances, only 5 mL accurately represents the amount of liquid in one teaspoon.
