Desired Dough Temperature Calculator
Find the water temperature that lands your dough on target, using room and flour temperature, mixer friction and an optional preferment.
The desired dough temperature formula
Water temperature = desired dough temperature × factors − (room + flour + friction), where the factor count is 3. With a preferment it becomes 4 and the preferment temperature is subtracted too.
Example in °F: desired 76, room 75, flour 70, friction 24 → 76 × 3 − (75 + 70 + 24) = 59 °F water.
What is the friction factor?
Mixing warms the dough. The friction factor is how many degrees your mixer and recipe add. Measure it once: mix a dough, note its final temperature, and compute friction = dough × 3 − (room + flour + water). It is a temperature difference, so the calculator scales it correctly when you switch between °F and °C.
FAQ
Why does the calculator warn about the result?
If the water has to be below 0 °C or above 45 °C the plan is not practical. Chill the flour, use ice for part of the water, or aim for a different dough temperature.
Do I use the same friction factor by hand?
Not usually. Hand mixing adds little heat, so measure a separate friction factor for each mixer and method.
Is °C input different from °F input?
The formula is the same. Temperatures are converted internally and the friction factor is treated as a difference rather than a temperature.

How we make sure
We check this tool with the automated test suites linked below. Example checks are shown in their original language.
- Verification method
- Check the three-factor formula with a 76/75/70 °F and friction 24 example, the 4-factor preferment case, and a Celsius case converted from it.
- Comparison reference
- The formula and friction-factor definition published by King Arthur Baking, applied by hand.
- Verification scope
- Only these samples and boundaries are checked; this does not prove correctness for every input or guarantee a bake.

- desired dough temperature: three-factor Fahrenheit example 76F target gives 59F water
- desired dough temperature: the same dough in Celsius agrees after conversion
- desired dough temperature: preferment adds a fourth factor
- desired dough temperature: unreachable water temperatures are flagged
These checks cover the listed examples and boundaries, not every possible input. Round trips and checks using the same library are not independent verification.
