How it's calculated

Sodium chloride is NaCl. With atomic masses of 22.990 (sodium) and 35.453 (chlorine), one formula unit weighs 58.443, so salt is 60.66% chloride and 39.34% sodium by weight. These figures are for pure sodium chloride. Road salt also contains some moisture and other minerals, so use your supplier's analysis for exact reporting.

Note: Chloride from road salt does not break down, so agencies often track tonnes of chloride as well as tonnes of salt.
