Cwt. is a hundred weight, or weight in hundreds of pounds. For example, 1 ton is 2000 lbs, which is equal to 20 Cwt. So a crop of tomatoes that weighs 14 tons (which is 14 * 2000 lbs, or 28,000 lbs) would be equal to 280 Cwt. At least that is in the United States. In the British system hundredweight is 112 lbs. Go figure. Anyway, Cwt in the U.S. is called short hundredweight, while Cwt in the British system is called long hundredweight.
Exhibit materials don't just materialize. They start somewhere and arrive somewhere. Which means we need to know their weight in order to ship the stuff. CWT is hundred weight—a measurement used to determine the cost of drayage (e.g. drayage rate is $78.56 CWT, so…1,500 pounds of display property=$1,178.40)
