Water Temperature Calculator

It uses the classic bakery formula: target dough temperature × 3, minus flour temperature, minus room temperature, minus a friction factor for your mixer. The result is the water temperature that lands your dough at the target after mixing.

Mechanical mixing generates heat through friction, and stronger mixers generate more of it. This calculator adds 0°C for hand mixing, 8°C for a stand mixer, and 18°C for a spiral mixer, then subtracts that from the water temperature so the extra heat is already accounted for.

Most bread recipes aim for a final dough temperature (FDT) of 24–26°C (75–78°F). That range keeps fermentation predictable: warm enough for the yeast to work at a normal pace, cool enough that bulk fermentation does not run away from you.

Below about 5°C the calculator flags the result as cold; above 35°C it flags it as warm. Very cold water usually means your kitchen or flour is already warm, so ice water or a chilled mixing bowl can help. Very warm water often shows up in cold kitchens and can accelerate fermentation more than expected, so watch the dough rather than the clock.

Yes, for the flour and room temperature inputs. An instant-read thermometer takes the guesswork out of both. Flour stored in a cool pantry or fridge can be several degrees off from the room around it, and that gap is exactly what this calculator corrects for.

Yes. Enter the temperature you want your levain or preferment to land at instead of the final dough. Slow, cool overnight builds usually target the lower end of the FDT range; same-day builds can run a couple of degrees warmer.
