Grain: The grain is a unit of mass primarily used for measuring the weight of small objects or quantities, especially in the context of bullets, ammunition, and some food products. One grain is approximately equal to 0.0648 grams.
In the United Kingdom, a "hundredweight" (abbreviated as cwt) is a unit of weight or mass used in various industries and commerce. However, it's important to note that the UK hundredweight is different from the US hundredweight in terms of its value.
In the United Kingdom:
1 hundredweight (UK) = 112 pounds (lbs)
So, while the US hundredweight is equal to 100 pounds, the UK hundredweight is equal to 112 pounds. This difference in value is important to be aware of when dealing with weights and measurements, especially in international trade or when comparing British measurements to those used in the United States or other countries.
