Find your water temperature

Enter the temperatures in your kitchen. The calculator gives you a practical water-temperature estimate for mixing your dough.

Desired dough temperature, °C Room temperature, °C Flour temperature, °C Starter temperature, °C Mixing friction factor, °C

For a home stand mixer, start with 8–12 °C. For hand mixing, try 4–8 °C and adjust next time if needed.

This is a starting point — dough temperature is the final guide.

Recommended water temperature24 °C75 °F

Formula: desired dough temperature × 4 − room temperature − flour temperature − starter temperature − mixing friction.

Measure the dough after mixing.
If it is too warm or too cool, adjust your friction factor for the next bake.
