Below are the order of the units from largest to the smallest:<span>
m^3 = meters and is 1 meter^3 is equal to 1000 liters
L = Liters and 1 liter is equal to 10 deciliter
dL = decilter, 1 deciliter is equal to 10 centiliter
cL = centiliter, 1 centiliter is equal to 10 mililiter
mL = mililiter, 1 militer is equal to </span><span>1000.000 µl</span>
µl = micorlitre
