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.
