Full Description
Counting units vary across industries. Bakers use dozens, retail packs use cases, and historical references mention scores or gross. This converter keeps everyone aligned by translating them back to individual pieces.
Extend the unit list if you have niche bundles—just add them to the conversion table with the appropriate item count.
Because all conversions route through single units, chained conversions remain consistent and precise.
