If a patient requires 1.5 L of fluid daily, how many mL is that?

To convert liters to milliliters, it's essential to know the relationship between these two units of measurement. One liter is equal to 1000 milliliters. Therefore, to find out how many milliliters are in 1.5 liters, you can multiply the number of liters by 1000.

1.5 L is calculated as follows:

1.5 L × 1000 mL/L = 1500 mL.

So, the correct conversion shows that if a patient requires 1.5 liters of fluid daily, that is equivalent to 1500 milliliters. This understanding of unit conversion is crucial in healthcare settings where precise measurements of fluid intake and medication dosages are necessary.
