Rate path
The rate follows the labelled path described below. It expresses target units per source unit and is recalculated from current positive public observations.

BTC amount × current ETH-per-BTC rate = estimated ETH
The rate follows the labelled path described below. It expresses target units per source unit and is recalculated from current positive public observations.
ETH normally displays with 8 decimal places in this tool, while the calculation keeps additional precision until display rounding.
This direction begins with BTC and asks how much ETH the same cross-market value represents. It is useful for comparing two native network assets, but it does not exchange Bitcoin for ether or compare their security models.
Enter a Bitcoin amount above. The calculator translates it through the relevant public reference and displays an indicative amount in Ether. You can reverse the direction without leaving the page.
This is a ratio between two volatile assets. It does not use a fiat price and can move even when both assets rise or fall together.
Kraken's public ETH/BTC market expresses ether directly in bitcoin. Reversing the pair uses the reciprocal of that cross rate. No fiat assumption is needed, and both sides can change value at the same time.
Bitcoin is the native unit of the Bitcoin network. One BTC can be divided into 100,000,000 satoshis, and control depends on the keys required to spend its transaction outputs.
BTC is used to measure bitcoin balances, transaction outputs, fees and market prices. The protocol's issuance schedule is separate from the exchange rate shown by a venue. For a reproducible Bitcoin value, retain the BTC quantity, price pair, venue or index method, timestamp, and quote asset. A wallet balance and an exchange balance also have different custody evidence, even when both are written in BTC.
Ether is the native asset of Ethereum, a proof-of-stake smart-contract network. ETH pays network fees and participates in staking and application markets.
An ETH conversion can compare Ethereum's native asset with bitcoin, fiat or another supported market unit. An ether cross should identify whether it comes from ETH/BTC, ETH/USD, ETH/USDT, or more than one visible leg. That path matters because each order book can have a different timestamp and liquidity, while an ETH amount also carries separate network, staking, contract, and custody risks.
The page answers a unit question only. It cannot decide whether either asset, venue, custody method or transaction is suitable for a reader.
BTC: BTC has no central price and can move sharply. A conversion says nothing about custody, transaction finality, taxes or whether a purchase suits a reader.
ETH: ETH and BTC are both volatile. Cross rates also reflect separate consensus, issuance, application and governance risks.
Spread, order-book depth, slippage, funding charges, withdrawal fees and taxes remain outside the calculation.
Examples use the current public reference when it is available.

Bitcoin is the native unit of the Bitcoin network. One BTC can be divided into 100,000,000 satoshis, and control depends on the keys required to spend its transaction outputs.

The BTC-to-ETH result excludes spread, trading and payment fees, slippage, withdrawal costs, taxes, and any provider minimum. Bitcoin.now cannot place or settle an order.
Each venue has its own BTC/ETH order book, liquidity, spread, timestamp, and fees. The displayed public reference is therefore an estimate, not a guaranteed executable value.
This direction begins with BTC and asks how much ETH the same cross-market value represents. It is useful for comparing two native network assets, but it does not exchange Bitcoin for ether or compare their security models.
Preserve the bitcoin amount exactly as recorded. The calculator does not inspect a wallet, prove ownership, or assume that the BTC is available on an exchange.
The public cross states BTC per ETH, so a BTC-to-ETH estimate uses its reciprocal to express ETH per BTC. That arithmetic does not add fiat or a stablecoin leg.
The result is an ether quantity before spread, fees, and slippage. It says nothing about Ethereum staking, smart contracts, transaction fees, or the custody needed to receive ETH.
