How many decimal places would you move from mm to liters?
Milimeters (mm) are a unit of length, whereas Liters (L) are a
unit of volume,l so it is impossible to switch between the two. You
can switch from milimeters to meters by moving the decimal three
places to the left. Conversely you can switch mililiters to liters
with the same method. This is because there are 1000 milimeters in
one meter and 1000 mililiters in one liter. When in doubt list and
cancel the units
