Source: fixed Ethereum unit definitions. Calculation runs locally; no live network data or exchange rate is used.
Check the method before using a result.
How it works
One ETH equals 1,000,000,000 Gwei or 1,000,000,000,000,000,000 Wei. One Gwei equals 1,000,000,000 Wei. The converter scales a decimal input to an integer Wei value, then formats the other units. It never rounds a valid input.
Example
Entering 2.5 Gwei returns 2,500,000,000 Wei and 0.0000000025 ETH. These are unit conversions, not a current gas quote or transaction fee.
Frequently asked questions
Is this the fee I will pay?
No. A transaction fee also depends on the gas used and the network's gas price at execution time.
Does this converter use live blockchain data?
No. The unit definitions are fixed, so a live API is unnecessary.
