What is the total volume in mL of 1.5 liters of fluid?

To determine the total volume in milliliters (mL) when given a measurement in liters, it is essential to know the conversion factor between these two units. One liter is equivalent to 1000 milliliters. Therefore, to convert 1.5 liters into milliliters, you multiply the number of liters by 1000:

1.5 liters × 1000 mL/liter = 1500 mL.

This calculation shows that 1.5 liters is equal to 1500 milliliters, which confirms that the correct answer is indeed the total volume of 1500 mL. Understanding unit conversion is crucial in dosage calculations, as nursing often requires precise measurements for medication administration.
