Denominations

The Basics

A denomination is a proper description of a currency amount. It is oftentimes a sub-unit of the currency. For example, traditionally a cent is 1/100th of a particular unit of currency.).

Monero denomination names add SI prefixes after dropping the initial "mo" for ease of use. Actually, the smallest unit of Monero is 1 piconero (0.000000000001 XMR).
