  • Liters to Tons / Tons to Liters Converter

    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. It's important to ensure that the density figure has been converted to liters per ton first.
