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 term "ton assay" in the context of the United States typically refers to the assay ton, which is a unit of measurement used in the mining industry to express the amount of valuable material contained in a quantity of ore. This measurement is particularly common in the context of precious metals like gold and silver.
An assay ton is defined as 29.1667 grams (or approximately 1.04 ounces) of ore material. Miners and metallurgists use this unit to represent a standardized sample size for the purposes of analyzing the ore's composition and determining the percentage of valuable minerals or metals within it.
The use of the assay ton is essential in assessing the economic viability of mining operations and estimating the potential yield of valuable minerals from a given ore deposit. By analyzing a sample that is equivalent to one assay ton, miners and analysts can extrapolate the likely yield from a larger quantity of ore.
So, when you encounter the term "ton assay US," it generally refers to the assay ton used in the United States for mineral analysis and mining-related calculations.
