What is the total number of milliliters in 3 L?

To convert liters to milliliters, it is essential to remember that 1 liter is equivalent to 1000 milliliters. Therefore, to find out how many milliliters are in 3 liters, you multiply the number of liters by 1000.

When you perform the calculation:

3 L × 1000 mL/L = 3000 mL.

This shows that the total number of milliliters in 3 liters is 3000 mL, confirming that the correct answer is indeed 3000 mL. This conversion is a fundamental concept in medical math, especially in contexts involving medication dosage and fluid measurements in clinical settings.
