If pure water is being measured, one ton equals 907.184 liters. In order to fully convert one ton to liters, however, the density of the liquid being measured must be known.
To find the number of liters in a ton, tons must first be converted to grams. One ton equals 2,000 pounds, and one pound equals 453.592 grams. Therefore, one ton equals 2,000 x 453.592, or 907,184 grams.
Next, multiply this number of grams by the density in grams per milliliter.
As one liter equals 1,000 milliliters, the result in milliliters is then divided by 1,000 to get the final result in liters.
