Converting Liters to Milliliters

The method to convert liters to milliliters is demonstrated in this worked example problem.

Problem:

How many milliliters are in a 5.0-liter canister?

Solution:

1 liter = 1000 mL

Set up the conversion so the desired unit will be cancelled out. In this case, we want mL to be the remaining unit.

Volume in mL = (Volume in L) x (1000 mL/1 L)
Volume in mL = 5.0 L x (1000 mL/1 L)
Volume in mL = 5000 mL

Answer:

There are 5000 mL in a 5.0-liter canister.
