How to Calculate CWT

by Kenneth Coppens; Updated September 26, 2017

CWT is the abbreviation for hundredweight. The C in the abbreviation stands for centum, Latin for "hundred." In the U.S, one CWT is equal to 100 pounds; in the UK, a CWT is known as a long hundredweight and weighs 112 pounds. The CWT system originated in Europe centuries ago; it's still in use in many industries, including farming and transportation, because it works. If you're in an industry that uses CWT, it's critical that you know how to calculate it. Converting the total weight of your product into CWT makes it simpler to determine its cost of production as well as the price you should charge to realize a good profit. Once you have weighed your product, calculating the CWT can be done in less than a minute.

Items you will need

  • Scale
  • Pen
  • Paper
  • Calculator
Step 1

Weigh the product. Unless you have a very large scale, you need to weigh a little bit at a time. Write down the total of each weigh-in.

Step 2

Add up the numbers from each weigh-in to get the total weight of your product. Use a calculator to prevent the risk of mistakes. Add it up three times to ensure the numbers are correct.

Step 3

Divide the total weight by 100. This number is the total amount of CWTs. Thus, 3 tons of corn equals 6,000 pounds, or 60 CWT.

Tips

  • If using the British Imperial System, divide the total weight by 112. This is a long CWT and is the basis for the long ton, or 2,240 pounds (112 pounds x 20 long CWT). In places where both measurements are sometimes used, such as parts of Canada, the 100-lb. CWT is commonly called a short CWT.
