What Are the Different Units Used in Ethereum?

When using Ethereum, you may encounter different units, such as Wei and Gwei. In this article, you'll find an explanation of the different units used, and a converter for all the different units.

The smallest unit is Wei. One Wei is equal to 0.000000000000000001 (or 10-18) Ether. The EVM (Ethereum Virtual Machine) uses Wei as base unit, since it is unable to deal with decimal numbers. Gwei, another common unit, primarily used for gas, is equal to 1000000000 Wei, or 0.000000001 (or 10-9) Ether. Below you will find a table, with all the other units and their respective value.

Some of these unit names refer to people that played a significant role in the creation of the computer, or in the development of the blockchain, such as Wei Dai, Charles Babbage, Ada Lovelace, Claude Shannon, Nick Szabo, and Hal Finney. Most of these unit names are not commonly used though, and in most cases it's best to stick to Wei, Gwei and Ether.
