How many pounds per kiloliters?
You cannot accurately answer that question since all liquids have a different density (mass per unit volume); however if you are using water that weighs 8.34 lbs/gallon, you can make that calculation. One gallon of water weighs 8.34 lbs/gallon and there are 3.784 liters per gallon so 2.2 lbs per liter or multiplying by 1000= 2,200 pounds per kiloliter or a long ton. Other conversions: 8.34 /2.2 = 3.785 kilos per gallon. Now convert gallons to liters 1 gallon = 3.785 liters Now 1000 * 3.785 = 3,785
