How to convert liters to tons. The ton is a unit of mass/weight and the liter is a unit of volume. To convert between the two, you need to know the density of the substance that you are trying to convert. To find out the mass in tons, multiply your volume in liters by the density of the substance (in tons per liter). Mass = Density × Volume.
