Gwei to USD converter
Gwei to USD conversion divides gwei by 1,000,000,000 to get ETH, then multiplies by the ether price. At $2,098.89 per ETH on CoinGecko, the gas price on Ethereum at this check is 0.08 gwei.
How to Use the Gwei to USD Converter
The gwei to USD converter takes a number in any of four units, wei, gwei, ETH or US dollars, and fills in the other three at today's ether price. The price is CoinGecko's, checked daily, and it matches the $2,098.89 in the fact box.
- Type a gas price in gwei to see what one gwei is worth in dollars.
- Type a fee in gwei (gas price times gas used) to see it in ETH and dollars.
- Type a wei value from a contract or an explorer to read it as ETH.
The tool also shows today's network gas price, 0.08 gwei, read from a public Ethereum RPC, so you can start from a real number.
Gwei to ETH and Wei to ETH
Gwei to ETH means dividing by 1,000,000,000, and wei to ETH means dividing by 1,000,000,000,000,000,000. The ethereum.org denominations table lists wei as 10^-18 ETH, the smallest amount of ether, and gwei (giga-wei) as 10^-9 ETH, the unit people use for gas fees.1
Contracts and RPC calls return values in wei because they work in whole numbers. Wallets and fee trackers show gwei because a gas price written in ETH would carry eight or nine zeros after the decimal point.
| Unit | In ETH | In wei |
|---|---|---|
| wei | 0.000000000000000001 | 1 |
| gwei | 0.000000001 | 1,000,000,000 |
| ETH | 1 | 1,000,000,000,000,000,000 |
How the Gwei to USD Math Works
Gwei to USD math is one line: gwei ÷ 1,000,000,000 × ETH price. A fee needs one more step first, because ethereum.org's gas page gives the fee as gas used times the base fee plus the priority fee.2
- Multiply the gas used by the gas price in gwei to get the fee in gwei.
- Divide by 1,000,000,000 to get the fee in ETH.
- Multiply by the ETH price to get the fee in dollars.
As an example with round numbers: a plain ETH transfer uses 21,000 gas. At a gas price of 20 gwei that is 420,000 gwei, or 0.00042 ETH. At an example ETH price of $2,000, the fee is $0.84. At that same example price, 1 gwei is worth $0.000002. These figures show the formula; today's gas price and ETH price are in the fact box.
Ethereum Gas Price in Gwei Today
The Ethereum gas price at this check is 0.08 gwei, read with an eth_gasPrice call to a public RPC. The base fee part is set by the protocol and the priority fee is a tip to validators, so the price a wallet suggests can sit a little above the network figure.
A transaction that runs a contract, such as a token swap, uses more than the 21,000 gas of a plain transfer, and ethereum.org notes that gas the transaction does not use is refunded. The gas fees explainer covers why prices rise when blocks fill up, and the gas fee calculator works out a full transaction cost. The Ethereum chain page lists RPC URLs and explorers.
Questions People Ask About Gwei to USD converter
These are the questions people ask next about Gwei to USD converter.
How much is 1 gwei in USD?
1 gwei in USD is the ETH price divided by 1,000,000,000. With ETH at $2,098.89 at this check, one gwei is a tiny fraction of a cent. Gas fees add up because a transaction pays the gas price for every unit of gas it uses.
How many gwei are in 1 ETH?
There are 1,000,000,000 gwei in 1 ETH, according to ethereum.org, which lists gwei as 10^-9 ETH. That makes 1 gwei equal to 0.000000001 ETH.
How do I convert wei to ETH?
To convert wei to ETH, divide the wei value by 1,000,000,000,000,000,000 (10^18). Smart contracts and RPC calls report balances in wei, so a balance that looks huge in wei is often a small amount of ETH.
What does gwei stand for?
Gwei stands for giga-wei, meaning one billion wei. ethereum.org describes it as the unit used for human-readable gas fees, while wei is the smallest unit of ether used in technical work.
