If you require large amounts of salt to use in industrial processes, to spread on city streets during the winter to melt snow and keep it from refreezing, or for other purposes, you may need to convert cubic yards of rock salt into tonnage for your calculations. A cubic yard is a volume measuring one yard in width, length and height. One cubic yard of rock salt is equivalent to 1.1 tons, according to the Minnesota Local Road Research Board's "Minnesota Snow and Ice Control" manual.
