Ethereum Unit Conversion Explained
Ethereum uses a hierarchical unit system: Wei (smallest), Gwei, and Ether. 1 Ether = 10^9 Gwei = 10^18 Wei. Smart contracts and the EVM work exclusively in Wei. This converter lets you enter a value in any unit and instantly see the equivalent in all three.
Use it when reading blockchain data, calculating gas costs, or converting between human-readable amounts and on-chain values. All conversion runs in your browser with BigInt for full precision.
When to Use Each Unit
Wei: Raw blockchain values, smart contract inputs, and precise calculations. Gwei: Gas prices — wallets and block explorers typically show gas in Gwei. Ether: Human-readable amounts for transfers, portfolio values, and UI display.
This tool accepts input in any unit. Type 1 in Ether to see 10^18 Wei and 10^9 Gwei. Type 21000 in the gas limit field of a Gas Fee Calculator, then 30 in Gwei, to estimate a simple transfer cost.
Quick Reference Table
Common conversions: 1 Wei = 0.000000001 Gwei = 10^-18 ETH. 1 Gwei = 10^9 Wei = 10^-9 ETH. 1 ETH = 10^18 Wei = 10^9 Gwei. A typical ETH transfer uses 21,000 gas; at 30 Gwei that's 630,000 Gwei = 0.00063 ETH. The quick reference table on this page shows these and other common values at a glance.
