What is this OP to ETH converter for?
This free OP to ETH converter is for rebalancing and research: compare Optimism against Ethereum as one mid-market ratio without opening a trading app. Live mid-market print: 1 OP ≈ 0.000048244 ETH. OP Superchain narratives do not lock this print — confirm the book you will use. Ethereum quotes move with gas and DeFi flows; size here, then check gas before any on-chain move.
Enter a OP amount, read the monospace ETH result, and skim the 7-day OP/ETH chart for recent context. The tool is free, works on mobile, and does not need an account.
The printed OP→ETH 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 OP/ETH portfolio slice with one mid-market ratio before you bridge or swap.
- Do quick mental math for a Optimism→Ethereum hop without opening a trading app.
- Compare research sizes when both legs move independently of a single fiat quote.
- OP Superchain narratives do not lock this print — confirm the book you will use.
How we get the OP/ETH rate
Both optimism and ethereum are priced through CoinGecko (direct vs_currency when available, otherwise a consistent bridge) so OP/ETH stays one number.
Server data for OP/ETH 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 OP/ETH 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 OP to ETH examples
Using the live mid-market print (1 OP ≈ 0.000048244 ETH), here are sample OP→ETH conversions. Enter any amount in the widget above for your own figure.
- 0.01 OP ≈ 0.0000004824 ETH at the current mid-market print.
- 0.1 OP ≈ 0.0000048244 ETH at the current mid-market print.
- 1 OP ≈ 0.000048244 ETH at the current mid-market print.
- These OP→ETH figures are mid-market estimates only — exchange spreads, withdrawal fees, and network gas are not included.
What can differ from the mid-market OP to ETH number
Cross rates move with liquidity on both Optimism and Ethereum. OP Superchain narratives do not lock this print — confirm the book you will use. Spreads, withdrawal fees, and network costs on either leg can leave you short of the mid-market number.
If you bridge OP→ETH through a third asset or CEX hop, each leg adds slippage. Confirm the executable path on the venue you will use.
After you know the OP/ETH rate, open the profit calculator for fee-aware P&L, the gas tracker before an on-chain move, or related pairs below. Read mid-market vs exchange rate when you need methodology. Not financial advice.
