This example problem demonstrates how to convert milliliters to liters. Problem A soda can holds 350 ml of liquid. If someone were to pour 20 soda cans of water into a bucket, how many liters of water are transferred to the bucket? Solution First, find the total volume of the water.Total volume in ml = 20 cans x 350 ml/canTotal volume in ml = 7000 ml Second, convert ml to L:1 L = 1000 ml Set up the conversion so the desired unit will be cancelled out. In this case, we want L to be the remaining unit.volume in L = (volume in ml) x (1 L/1000 ml)volume in L = (7000/1000) Lvolume in L = 7 L Answer 7 liters of water was poured into the bucket.
