Enter your desired dough temperature (DDT), air temperature, flour temperature, and water amount to find the exact water temperature needed. Optionally account for mixer friction and a sourdough starter to dial in your dough temperature with precision.

DDT (Desired Dough Temperature) is the target internal temperature you want your dough to reach immediately after mixing. Consistent dough temperature leads to predictable fermentation times, better gluten development, and more repeatable baking results. Most bread recipes target a DDT of 75–78°F (24–26°C).
Water is the easiest ingredient to adjust in a recipe because it can be heated or chilled easily. Since you can't quickly change the temperature of your flour or kitchen, adjusting water temperature is the primary lever bakers use to hit their DDT. Even a few degrees off can shift fermentation timing significantly.
Mixer friction factor (also called friction heat) is the heat generated by a stand mixer's mechanical action during mixing. It typically ranges from 18–24°F (10–13°C) for most home stand mixers on a standard mix. To measure it precisely, mix dough and record dough temperature before and after — the rise is your friction factor.
Always use the actual measured flour temperature for accuracy. Flour stored in a pantry, refrigerator, or warm kitchen can vary widely from room temperature. Use an instant-read thermometer to measure your flour directly for the most precise water temperature calculation.
Starter (or any preferment) contributes its own temperature to the final dough mass. If you're using a significant amount of starter — say 20% of total dough weight or more — its temperature meaningfully shifts the heat balance. This calculator accounts for starter weight and temperature to give you a more accurate water temperature target.
Extreme results usually mean your kitchen or flour is at an extreme temperature. If the required water temperature is above 95°F (35°C), consider using cooler flour, lowering your kitchen temperature, or splitting your water into a hot/cool mix. If it's below 32°F (0°C), try using ice water or pre-chilling your flour in the refrigerator.
Switch the Temperature Unit toggle to °C before entering your values, and all inputs and outputs will be in Celsius. The formula adjusts automatically — no manual conversion needed.
Yes — DDT and FDT are two terms for the same concept. Some bakers and recipes use 'Final Dough Temperature' to emphasize it's measured right after mixing is complete, while 'Desired Dough Temperature' is more commonly used in instructional contexts. They refer to the same target.
