In the United States, a "quarter" is a common informal term used to refer to a quarter of various units of measurement, such as a quarter of a dollar, a quarter of a year, or a quarter of other divisible quantities. However, when used in the context of weight or mass, a "quarter" typically refers to a quarter of a hundredweight (cwt).
Since a hundredweight (cwt) in the United States is equal to 100 pounds (lbs), a quarter of a hundredweight is equal to:
1 quarter (US) = 25 pounds (lbs)
So, when you see "quarter" used in the context of weight or mass in the United States, it generally means 25 pounds. This term is often used informally, especially in agricultural or trade contexts, to refer to a convenient fraction of weight.
A dekagram (dag) is a metric unit of mass or weight in the International System of Units (SI). It represents ten grams or 10^1 grams. The metric system is a decimal-based system of measurement used worldwide, and it provides a convenient way to express both large and small quantities of mass.
To give you a better understanding of the dekagram's size:
Dekagrams are not as commonly used as some other metric units of mass like grams and kilograms, but you might encounter them in specific contexts, especially in culinary measurements for food ingredients. For example, some recipes or food packaging might express the weight of an ingredient in dekagrams, particularly in countries where the metric system is prevalent.
