Ethereum unit denominations

Ether (ETH) is the native currency of Ethereum. It is divided into smaller denominations. Wei is the smallest unit (1 ETH = 10¹⁸ Wei). Gwei (gigawei) is most commonly used for gas prices (1 ETH = 10⁹ Gwei). Solidity smart contracts work in Wei internally.

Common use cases

Use Gwei when reading gas prices. Use Wei when writing Solidity contracts. Use Ether for everyday amounts and wallet balances.
