Awater dispenser has a capacity of 20,000 milliliters. what is its capacity in liters?
be sure to include the correct unit in your answer.

20 Liters

Step-by-step explanation:

One way to look at it is that there are 1000 mL in one L.  But I think a better way in general for  unti conversions is to do it like this.

20000 ml * Where you can just cancel out the units.  Hopefully it made sense.  If you were converting from L to ml you would use

linear pair postulates
