A decagram is a unit of mass in the metric system that is equal to ten grams. It is often used in scientific contexts, particularly in chemistry and cooking, where precise measurements are important. The symbol for decagram is "dag." In the metric system, the decagram is part of a larger hierarchy of units, where one kilogram equals 1,000 grams. This makes the decagram a convenient measurement for small quantities, bridging the gap between grams and larger units like kilograms. Understanding decagrams can help in accurately measuring ingredients or substances in various applications.
