Which unit of measurement is used to express small volumes in a medical setting?

The unit of measurement used to express small volumes in a medical setting is milliliters. This metric unit is particularly advantageous when dealing with medications, IV fluids, and other solutions that require precise dosing. The milliliter is commonly used because it allows healthcare professionals to measure and administer small quantities of liquid accurately, which is crucial for patient safety and effective treatment.

Cubic centimeters are equivalent to milliliters, as 1 milliliter equals 1 cubic centimeter. However, milliliters are the more commonly used term in clinical practice, particularly when referring to medications. Liters and cubic meters are more suitable for larger volumes, and are not typically utilized for the small quantities often required in medical situations. Therefore, milliliters are the standard unit for expressing small volumes in a healthcare context.
