DAG stands for decagram in the metric system. A decagram is a unit of mass in the metric system equivalent to ten grams. The metric system is a decimal-based system that uses various prefixes to indicate multiples or fractions of base units.
The prefix ‘deca-‘ means ten times the base unit, which in this case is the gram. So when we talk about a decagram, we are referring to a mass that is ten times the weight of one gram. This unit is not as commonly used in everyday life, but it can be useful in fields like cooking or laboratory measurements where precise weights are necessary.
