What is the conversion factor from ounces to milliliters?

The conversion factor from ounces to milliliters is based on the fact that 1 fluid ounce is equivalent to approximately 29.57 milliliters. This precise conversion is crucial in nursing and medical settings where accurate medication dosages are necessary. As a standard method, rounding to 30 mL per ounce is often used for simplicity in calculations, but the exact figure of 29.57 mL provides a more accurate representation.

This conversion is important when preparing medications or fluids that require precise dosing, especially when switching between different measurement systems like the imperial system (ounces) and the metric system (milliliters). Understanding this conversion factor helps ensure that doses are correct, which can be vital for patient safety and effective treatment.
