Individual workers' wages are recorded on the DES wage record files and retained for five quarters to be used for determining monetary benefit entitlement should a worker file a claim for unemployment insurance benefits. The DES is required to establish and maintain a separate experience rate account for each employer.
In the United States and formerly Canada a ton is defined to be 2,000 pounds (907 kg). Where confusion is possible, the 2240 lb ton is called long ton and the 2000 lb ton short ton; the tonne is distinguished by its spelling, but usually pronounced the same as ton, hence the US term metric ton.
The short ton is based on the English measurement system and is equivalent to 2,000 pounds. Each pound is approximately 0.45 kilograms, thus the short ton is equivalent to 907 kilograms. The metric ton, also called the tonne, is based on the metric measurement system. A metric ton is equivalent to 1 megagram, or 1 million grams. Another type of ton is the long ton or U.K. ton, which is equivalent to 1,016 kilograms.
