What is this ETH to OP converter for?
This free ETH to OP converter is for rebalancing and research: compare Ethereum against Optimism as one mid-market ratio without opening a trading app. Live mid-market print: 1 ETH ≈ 20,750.35 OP. Ethereum quotes move with gas and DeFi flows; size here, then check gas before any on-chain move. OP Superchain narratives do not lock this print — confirm the book you will use.
Enter a ETH amount, read the monospace OP result, and skim the 7-day ETH/OP chart for recent context. The tool is free, works on mobile, and does not need an account.
The printed ETH→OP rate is not an order book, OTC desk, or P2P advert. Venue bid/ask and local premiums can differ. This is not financial advice.
- Rebalance a ETH/OP portfolio slice with one mid-market ratio before you bridge or swap.
- Do quick mental math for a Ethereum→Optimism hop without opening a trading app.
- Compare research sizes when both legs move independently of a single fiat quote.
- Ethereum quotes move with gas and DeFi flows; size here, then check gas before any on-chain move.
How we get the ETH/OP rate
Both ethereum and optimism are priced through CoinGecko (direct vs_currency when available, otherwise a consistent bridge) so ETH/OP stays one number.
Server data for ETH/OP revalidates about every 60 seconds; the widget refreshes in the background while the tab is open. If live data drops briefly, retry — a cached value may still show.
Converted amount = input × mid-market ETH/OP rate (or the inverse after you swap). We never hardcode prices. Stablecoins such as USDT still use the mid-market index — not a guaranteed $1 redemption.
Worked ETH to OP examples
Using the live mid-market print (1 ETH ≈ 20,750.35 OP), here are sample ETH→OP conversions. Enter any amount in the widget above for your own figure.
- 0.01 ETH ≈ 207.5 OP at the current mid-market print.
- 0.1 ETH ≈ 2,075.03 OP at the current mid-market print.
- 1 ETH ≈ 20,750.35 OP at the current mid-market print.
- These ETH→OP figures are mid-market estimates only — exchange spreads, withdrawal fees, and network gas are not included.
What can differ from the mid-market ETH to OP number
Cross rates move with liquidity on both Ethereum and Optimism. Ethereum quotes move with gas and DeFi flows; size here, then check gas before any on-chain move. Spreads, withdrawal fees, and network costs on either leg can leave you short of the mid-market number.
If you bridge ETH→OP through a third asset or CEX hop, each leg adds slippage. Confirm the executable path on the venue you will use.
