What is the milliliter equivalent of 1 teaspoon?

The correct equivalent of 1 teaspoon in milliliters is 5 mL. This measurement is based on standard conversions between common volume units used in cooking and pharmacy. In many contexts, such as medical dosages and culinary measurements, it is essential to have a clear understanding of such conversions to ensure accuracy in dosing and ingredient measurements.

1 teaspoon is commonly recognized as approximately 5 milliliters, making this conversion crucial for pharmacists and healthcare professionals when preparing medications or advising patients on dosages. Understanding this conversion also fosters safety in medication administration, as correct measurement is vital for efficacy and minimizing potential side effects.

Other choices like 3 mL, 10 mL, and 15 mL do not accurately represent the standard volume conversion for 1 teaspoon, thus emphasizing the importance of using the correct figure in practice.
