Gwei to USD Converter

Gwei is the unit gas prices are quoted in, but it means little until turned into dollars. This tool combines a gwei gas price with gas units and an ETH/USD price you supply to show the fee in USD. It runs entirely in your browser.

A plain ETH transfer costs 21,000 gas. Price is a manual input — this tool does no network call.

From gwei to dollars

One gwei is 10^-9 ETH, so a fee in ETH is gas_units times gas_price(gwei) times 10^-9. Multiplying that ETH amount by an ETH/USD price gives the dollar cost. Gwei alone is not a total; you need the gas units and a price to reach a USD figure.

You supply the price

The USD conversion uses an ETH/USD price you enter. The tool makes no network call and reads no price oracle, so the result reflects exactly the price you choose, which is useful for modeling different market conditions.

常见问题

Is gwei the same as the total fee?

No. Gwei is the price per unit of gas. Multiply by gas units and 10^-9 to get ETH, then by the ETH/USD price for dollars.

Does the tool look up the ETH price?

No. You provide the ETH/USD price manually. There is no network call and no API key.
