If you have 3 liters of a fluid, how many milliliters do you have?

To convert liters to milliliters, it's important to remember that 1 liter is equal to 1,000 milliliters. Therefore, to find out how many milliliters are in 3 liters, you would multiply the number of liters (3) by the conversion factor (1,000 mL/L).

So, the calculation would be:

3 liters × 1,000 milliliters/liter = 3,000 milliliters.

This means that in 3 liters of fluid, there are 3,000 milliliters. Thus, the correct answer is the one that reflects this multiplication. Understanding this conversion is crucial, as it frequently appears in medical and laboratory contexts where precise measurements of fluids are often necessary.
