How to convert gwei or wei to ETH
Divide gwei by 1 billion to get ETH. Divide wei by 1 quintillion (1,000,000,000,000,000,000) to get ETH. To go the other way, multiply by the same number.
Wei is the smallest unit of ETH. One gwei equals 1 billion wei.
If your wallet shows a gas price of 10 gwei, that’s the price of one unit of gas. If the transfer uses 21,000 gas, multiply to get 210,000 gwei, or 0.00021 ETH. If you already have a total fee in wei or gwei, you can convert it directly above.
Open the 21,000 gas example in the fee calculator. If you’re working from a receipt, check which gas numbers to enter.
