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.
How many kilograms are in a metric ton? To differentiate between the different tons, the system has come up with the long ton, tonne and short ton. The long ton weighs 2,240 pounds, the tonne weighs 1,000 kilograms (2,204.6 pounds) and the short ton weighs 2,000 pounds (907.2 kilograms). The long ton and the tonne are commonly used in the United Kingdom for trade. The short ton is used in the United States.
