Practical tools

Sourdough calculators and baking math

Sourjoe calculators are built for baking decisions: converting units, exploring recipe changes, understanding hydration, and reducing guesswork when designing or adjusting dough.

Unit conversion

The public preview includes the Unit Converter as a live calculator sample. It helps translate practical kitchen measures while keeping the baker oriented in the recipe.

Baker's math

Sourdough formulas are easier to adjust when flour is treated as the reference point. Calculators can help bakers reason about hydration, salt percentage, starter percentage, and yield.

What-if thinking

Calculators are useful for controlled experiments. Changing one variable at a time makes it easier to understand how a formula behaves.
