In the United States, a "hundredweight" (abbreviated as cwt) is a unit of weight or mass used in various industries, especially in agriculture and commerce. The hundredweight is equivalent to 100 pounds (lbs). It is often used to express weights or quantities of goods, particularly in contexts like the sale of agricultural products, grains, and some industrial materials.
1 hundredweight (US) = 100 pounds (lbs)
Hundredweights are commonly used in trade and commerce, especially for bulk items where the use of pounds or tons may not be as convenient. It provides a middle-ground unit for measuring weight between the pound and the ton. When you see prices or quantities listed in hundredweights in the United States, it means that they are referring to units of 100 pounds each.
The "ton assay" or "ton assay UK" typically refers to the assay ton, a unit of measurement used in the mining industry to express the amount of valuable material contained in a quantity of ore. This unit of measurement is used similarly in both the United States and the United Kingdom.
An assay ton is defined as 29.1667 grams (or approximately 1.04 ounces) of ore material. It is a standardized sample size used for analyzing the composition of ore and determining the percentage of valuable minerals or metals present within it.
Miners and metallurgists use assay tons to assess the quality and economic potential of ore deposits. By analyzing a sample equivalent to one assay ton, they can estimate the likely yield of valuable minerals from a larger quantity of ore.
So, "ton assay UK" refers to the assay ton measurement used in the United Kingdom, which is the same as the assay ton used in the United States and other mining contexts.
