Read the ETH to Bitcoin close ratio
Compare how much Bitcoin corresponds to one Ether using original Coinbase USD daily closes from the same completed UTC bucket. Keep both originals, their source evidence and the explicit rounding rule.
1. Understand this derived ETH/BTC value
Datisto divides the original Coinbase Exchange ETH-USD daily close by the original BTC-USD daily close. The USD units cancel, leaving BTC per one ETH. This is a named calculation from two USD markets, not an executed trade or an executable quote in a directly traded ETH-BTC market. Neither spot spread, fees nor trading slippage are included.
2. Match the exact completed UTC bucket
Both inputs must describe the same 24-hour UTC bucket, the same venue, original unadjusted prices and the correct Bitcoin and Ethereum identities. Each close is the source-reported close within its own daily bucket; matching buckets do not prove that the last trades occurred simultaneously. Missing one exact input leaves a visible gap, without borrowing the previous day or another exchange.
The initial interval uses the latest common stored ETH and BTC coverage, bounded to at most 90 days. Each ratio cell needs both original daily closes; missing values are not filled. Latest value, history and table share one result. Presentation changes do not switch the source.
3. Read precision and unavailable values
The original decimal strings enter exact rational division. Datisto rounds once to at most 18 decimal places using HALF_UP and removes trailing zeros. The rounding indicator is true when a nonzero remainder was discarded at that precision; a displayed value is not presented as infinitely exact. Original prices retain every supplied digit.
A genuinely usable zero ETH close gives ratio zero when the BTC denominator is positive. A zero BTC denominator, missing original, unusable quality or out-of-budget ratio is unavailable with a reason. An unavailable value never becomes zero. The calculation does not infer a future price or an investment recommendation.
4. Inspect the two originals and capture clock
Open Value Passport from a ratio cell to inspect both original OHLCV points in one verified read: Ether is the numerator and Bitcoin the denominator. The retained source bundle has its own capture clock and checksum. That bundle clock is not the time of both closing trades or a proven first publication. Individual source publication and revision clocks remain unknown.
