How many milliliters are equivalent to one teaspoon?

One teaspoon is equivalent to 5 milliliters. This standard measurement is often used in both cooking and pharmacology to ensure accuracy in dosing and recipe preparation. Understanding this conversion is essential for medication aides as they need to accurately measure liquid doses. Being familiar with such conversions helps prevent medication errors, ensuring patient safety and effective treatment. The other options do not represent the correct conversion for a teaspoon, as they either understate or overstate the volume related to that measurement.
