Explanation

Formula: Brew Ratio 1:15 = Brew Ratio 1:17 × 0.882353. Why: brew-ratio notation is normalized through grams of coffee per liter of water, so the route compares fixed ratio definitions on one extraction-strength basis.

Brew Ratio 1:17: a brew-ratio format interpreted as grams of water per 1 gram of coffee, then normalized to a grams-per-liter coffee dose basis.

Brew Ratio 1:15: a brew-ratio format interpreted as grams of water per 1 gram of coffee, then normalized to a grams-per-liter coffee dose basis.

This route is useful when comparing brew-ratio recipes such as 1:15, 1:16, and 1:18 on one common extraction-strength basis.

This conversion is purely multiplicative because both formats reduce through grams of coffee per liter of water, with fixed cup-size assumptions where those formats apply.
