How to use the desired dough temperature calculator
- Choose Fahrenheit or Celsius, then enter the dough temperature you want right after mixing.
- Enter the flour temperature and the room temperature.
- Enter your mixer friction factor, the number of degrees your mixing adds. Measure it once for your own mixer and method.
- For a dough with a starter, poolish or biga, choose the four factor method and enter the preferment temperature. Read the water temperature.
Formula
three factors: water = 3 x desired - flour - room - friction
four factors: water = 4 x desired - flour - room - preferment - friction
check: (flour + room + friction + water [+ preferment]) / factors = desired
The idea is that the dough ends at the average of its factors. The water makes up whatever the other factors do not supply.
A dough with a 76 degree target
You want a dough temperature of 76°F. The flour is 68°F, the room is 72°F and your mixer friction factor is 24°F. Water = 3 x 76 - 68 - 72 - 24 = 64°F. The check averages 68, 72, 24 and 64 over three factors and gets 76°F.
With a preferment at 78°F, use four factors: 4 x 76 - 68 - 72 - 78 - 24 = 62°F. In Celsius, a target of 24°C with flour at 20°C, a room at 22°C and a friction factor of 13°C gives 3 x 24 - 20 - 22 - 13 = 17°C. If the result is below freezing, the page says so and suggests ice for part of the water.
Finding your friction factor
Mixing warms dough, and how much depends on your mixer, the speed, the time and the size of the batch. To find your factor, mix a batch with water at a temperature you choose, measure the dough, and work backward: friction = 3 x dough temperature - flour - room - water. Use the same mixing method afterward and the value stays close.
Hand kneading adds far less heat than a stand mixer. If you mix by hand, your factor may be small. If you are not sure, start with 0 and adjust after measuring.
Why dough temperature matters
Dough temperature controls how fast yeast and bacteria work, so a consistent temperature gives consistent timing for fermentation and proofing. Bakers aim for the same temperature after mixing from batch to batch, and change the water to cover swings in the flour and room. For recipes in bakers percentages, see the Bakers Percentage Calculator, and for starters the Sourdough Hydration Calculator and the Poolish and Biga Calculator.
Assumptions and limits
- The dough ends at the simple average of the factors, which is an approximation that works well in practice.
- The friction factor is entered by you and is specific to your mixer and method.
- The temperatures in the fields are examples. Use readings from a thermometer for your own flour and room.
- The page does not check food safety or yeast limits. Very hot water can harm yeast, so check your recipe.
Frequently asked questions
What is a good dough temperature?
It depends on the dough and the schedule you want. Many recipes name a target after mixing, and the right value is the one your recipe or your own tests call for. This page helps you hit whatever target you choose.
What if the water temperature comes out below freezing?
Plain water cannot go below freezing, so replace part of the water with ice or use cooler flour or a cooler room. The page warns you when the result is not possible for liquid water.
When should I use the four factor method?
Use it when a significant part of the dough is a preferment such as a poolish, biga or sourdough starter, because its temperature affects the final dough as much as the flour does.
Does this work in Celsius?
Yes. Choose Celsius and enter all temperatures in Celsius. A friction factor measured in Fahrenheit must be divided by 1.8 before you use it in Celsius.
