A decigram (dg) is a unit of mass in the metric system that is equal to one-tenth (1/10) of a gram. This means that there are ten decigrams in a gram. It is not a unit commonly used in everyday life, but it can be found in scientific and medical contexts where precise measurements are necessary.
To put it in perspective, if you have a standard paperclip, which usually weighs about one gram, it would weigh ten decigrams. The decigram is part of the metric system which is widely used around the world due to its ease of conversion and standardization.
