Plural of decigram; multiple units of mass equal to one-tenth of a gram each.
Simply the regular plural form of 'decigram,' formed by adding '-s.' No special etymology beyond the base unit's origin in the metric system.
Even though decigramsare a perfectly logical metric unit, they're rarely used in practice—we usually jump straight from grams to milligrams, skipping the decimal divisions. It's like the metric system created a ladder with all the rungs, but we only use every other one.
