How many milliliters are in 1 teaspoon?

In medical and pharmaceutical contexts, it's essential to have a clear understanding of common measurements used in dosing. One teaspoon is equivalent to 5 milliliters. This conversion is widely accepted in both clinical and culinary settings, facilitating accurate medication administration and safe dosages. The standardized measurement of 5 ml helps prevent dosing errors, which can pose risks to patient safety.

Understanding these units and their conversions is crucial for healthcare professionals, as it ensures precise communication regarding doses prescribed or dispensed. Other conversions, such as 2 ml, 10 ml, or 15 ml, do not align with the established measurement for a teaspoon, making them less applicable in this scenario.
