Explanation

Formula: Brew Ratio 1:18 = Brew Ratio 1:14 × 1.285714. 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 1:14: 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 1:18: 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.
