ETH to gwei converter
Convert ETH into gwei, the unit used for gas prices. One ether equals 10^9 gwei, so this tool multiplies your ether input by 1,000,000,000 to give the gwei value.

The exact relationship
1 ether = 10^9 gwei (1,000,000,000 gwei). To convert ETH to gwei you multiply by 1,000,000,000. So 0.00000003 ETH is 30 gwei and 1 ETH is 1000000000 gwei. Because gwei itself equals 10^9 wei, this sits exactly midway on the wei-gwei-ether ladder.
Where you hit this in real work
You reach for this when a fee or price is denominated in ETH but a tool or gas setting expects gwei. Converting a small ETH figure into gwei gives you the readable gas-price number that wallets and RPC gas fields use.
Frequently asked
What is 1 ETH in gwei?
1 ETH equals 1000000000 gwei, which is 10^9 gwei.
Is gwei the same as nano-ether?
Yes. Gwei is 10^-9 ether, so one gwei is a nano-ether, or a billionth of an ETH.
