A nurse needs to give a patient 0.4 L of saline. How many mL is that?

To determine the volume in milliliters (mL) when given a volume in liters (L), it’s essential to understand the conversion between these two units. One liter is equivalent to 1,000 milliliters. Therefore, to convert liters to milliliters, you multiply the number of liters by 1,000.

In this case, the nurse needs to administer 0.4 L of saline. Performing the conversion:

0.4 L × 1,000 mL/L = 400 mL.

This calculation shows that 0.4 liters is equal to 400 milliliters, making 400 mL the accurate conversion. Understanding the relationship between liters and milliliters is key in medical settings, as precise dosing is critical for patient safety.
