Bread Calculator
Scale bread recipes with baker's percentages, ingredient weights, dough weight, and hydration.

Baker's percentages
Flour is the 100% baseline. Changing a percentage updates that ingredient's grams, and changing grams updates the percentage, so a recipe can be scaled from either direction.
Hydration and preferments
Starter, leaven, and poolish are treated as 100% hydration preferments. Half of their weight counts as flour and half counts as water when calculating total hydration.
