If a Satoshi is the smallest unit of Bitcoin recorded on the Blockchain — a bit like the cent is the lowest tradable value of the United States Dollar — what is the smallest denomination of Ether? It's a Wei. Here's everything you need to know about it.
The smallest unit of Ether is a Wei, with one Ether comprising of 1,000,000,000,000,000,000. That eye-burning number is a whopping quintillion, so you'll need to amass that much Wei in order to come out with an Ether.
As is the case with Bitcoin and the Satoshi, since the value of a Wei is so low, it's rare you'll find a retailer listing them. Instead, all values for Ether are illustrated in ETH — unless you're trading microscopic amounts through exchange-based websites.
If you do happen to find yourself toying around with small denominations of Ether on an exchange, there are a number of other terms used to refer to small units of Ether you'll need to be familiar with, including Kwei, Mwei, Microether, and Milliether.
