The Oven SpringWater temperature calculator for bread
Estimate mixing-water temperature from your flour, room and desired dough temperature. Check the dough after mixing and adjust the next batch from that observation.
Mixing water: 90°F
4 × 78 − 72 − 72 − 78 − 0 = 90°F.
This is a practical estimate, not a heat-balance simulation.
How this estimate works
King Arthur’s desired-dough-temperature method uses three factors without preferment and four with it. Multiply desired dough temperature by that factor, then subtract flour temperature, room temperature, the mixing friction rise and, if used, preferment temperature. The method gives those factors equal weight; it does not calculate the thermal properties of every ingredient.
Friction depends on your mixer or hand-mixing process. Zero is only the starting example. Measure finished dough temperature, compare it with the target and refine the friction allowance on your next similar mix. Switching units converts temperatures with the freezing-point offset, but converts the friction rise by scale alone.
Use the result with your recipe
Do not use an extreme result to force a schedule. Check the inputs, ingredient temperatures and units first. Follow the recipe’s water and yeast instructions. A suitable thermometer lets you measure the dough instead of relying on the room thermostat.
Then plan your bulk and bake timeline. Need a different amount of preferment? Use the starter and levain calculator.
