Bread Baking Calculator | Water Temperature & Ice from Desired Dough Temperature, Baker's Percentage, Loaf Pan Specific Volume & Dough Weight, Yeast Conversion
The Bread Baking Calculator gathers the calculations you need before mixing bread dough. From the desired dough temperature (27°C for sandwich bread, 24°C for baguettes, and so on), the room and flour temperatures, and the temperature rise for hand kneading, a mixer, or a bread machine, it finds the water temperature with "(desired dough temperature − friction factor) × 3 − (room temperature + flour temperature)," and shows in grams how much ice you need in summer or hot water in winter. It also covers the ×4 formula for when you add a levain or sponge, and can work backward from your actual dough temperature to find the temperature rise of your own mixing method. The baker's percentage formula gives the grams of every ingredient starting from the flour weight, the final dough weight, pieces × grams each, or the weight of a single egg, and checks the effective hydration, which counts the water in milk, eggs, butter, and levain, along with the salt and sugar percentages. From a loaf pan's inside dimensions (or its volume measured with water) and the specific volume (3.8 for a Pullman loaf, 4.2 for a peaked loaf, and so on), it works out how much dough goes into the pan and turns it into a formula. It also converts between fresh yeast, active dry yeast, and instant dry yeast, converts teaspoons, tablespoons, and cups to grams, and shows how much milk or egg replaces water.
Calculate Water Temperature from Desired Dough Temperature
The speed of fermentation depends on the dough temperature at the end of mixing (desired dough temperature, DDT). From the room temperature, flour temperature, and the temperature rise during mixing, this finds what water temperature gets you to your target dough temperature.
Dough type (desired dough temperature)
Mixing method (temperature rise from friction)
Kneading on the bench for 10–15 minutes usually raises the dough 2–4°C above the average of the three temperatures
Dough Water Temperature
26℃
Mix with 26°C water
Warmer than tap water, so make lukewarm water. Use the hot water amount guide below.
Formula: (27 − 3) × 3 − (24 + 22) = 26°C
Amount of Ice or Hot Water
From the amount of dough water and the tap water temperature, this finds how many grams of ice to add (summer) or boiling water to mix in (winter).
Enter the amount of dough water to get the amount of ice or hot water.
Work Out the Temperature Rise from Your Last Result
Insert a thermometer into the center of the dough at the end of mixing and enter the reading to see how many degrees your own mixing method or bread machine adds. Next time, enter that value under "Set my own".
Enter the room and flour temperatures above, plus the actual dough temperature and the water temperature.

About Bread Baking Calculator | Water Temperature & Ice from Desired Dough Temperature, Baker's Percentage, Loaf Pan Specific Volume & Dough Weight, Yeast Conversion
The Bread Baking Calculator is a free tool that gathers the calculations you need before mixing bread dough. From the desired dough temperature, room temperature, flour temperature, and the temperature rise from your mixing method (hand kneading, mixer, or bread machine), it finds what temperature your dough water should be using "(desired dough temperature − friction factor) × 3 − (room temperature + flour temperature)," and shows in grams how much ice to add in summer or hot water to mix in during winter. Doughs with a levain or sponge use the ×4 formula that also counts the preferment temperature, and you can work backward from a measured dough temperature to find the temperature rise of your own mixing method. The baker's percentage formula gives the grams of every ingredient from the flour weight, the final dough weight, pieces × grams each, or the weight of a single ingredient such as one egg, and also checks the effective hydration, which counts the water in milk, eggs, butter, and preferment, along with the salt and sugar percentages. From a loaf pan's inside dimensions or volume and the specific volume, it finds how much dough goes into the pan and turns it into a formula. It also converts between yeast types and between teaspoons, tablespoons, and grams.

- I want the water temperature for a levain I just took out of the fridge
- I want to convert a baker's percentage recipe into grams for the 300g of flour or the one egg I have on hand
- I want to divide the dough into 8 pieces of 50g each and work out how much flour to prepare
- I want to know the effective hydration of a dough with milk and eggs so I can compare its stiffness with other recipes
- I want to know how many grams of dough go into a 1-loaf pan, a 1.5-loaf pan, or the loaf pan I own
- I want to make a fresh yeast recipe with instant dry yeast
Good to know
- The water temperature uses the formula commonly found in baking textbooks (water temperature = (desired dough temperature − friction factor) × 3 − (room temperature + flour temperature), or × 4 with the preferment temperature subtracted too). The temperature rise for each mixing method (hand kneading 3°C, mixer 6°C, bread machine 8°C) is only a rough guide, so measuring once and working backward to get your own value makes it more accurate.
- The ice amount assumes that ice at 0°C absorbs 80 cal per gram as it melts, and finds the amount that brings the water to the target temperature once fully melted. Ice from the freezer is colder than 0°C, so slightly less is enough in practice. When the water temperature comes out below 0°C, water alone can't get there, so the tool suggests other ways to bring the temperature down, such as chilling the flour or lowering the room temperature.
- Hot water above 40°C weakens yeast it touches directly, and above 50°C it kills the yeast. In those cases the tool shows a warning.
- Effective hydration counts milk as about 88% water, whole egg as about 75%, and butter as about 16%, and splits a levain into flour and water using the hydration you enter. The salt and sugar percentages are also calculated against the flour weight including the flour inside the preferment.
- The dough weight for a pan is "pan volume ÷ specific volume." Typical specific volumes are 3.6–4.0 for a Pullman loaf and 4.0–4.5 for a peaked loaf. To measure the pan volume, line the pan with a plastic bag, fill it to the rim with water, and weigh the water; its weight in grams can be used as milliliters.
- The yeast conversion is a rough guide of fresh yeast 3 : active dry yeast 1.5 : instant dry yeast 1. Measuring spoon weights are typical values for level measures and vary with how the ingredient is packed and with the product.

FAQ
- How do I calculate the dough water temperature?
- Use water temperature = (desired dough temperature − temperature rise from mixing) × 3 − (room temperature + flour temperature). For sandwich bread (target 27°C) hand kneaded (rise 3°C) with a 24°C room and 22°C flour, it is (27 − 3) × 3 − (24 + 22) = 26°C. When you add a levain or sponge, multiply by 4 instead and also subtract the preferment temperature.
- My dough gets too warm in summer. How many grams of ice should I add?
- A rough guide is ice amount = dough water × (tap water temperature − target water temperature) ÷ (tap water temperature + 80). With 180g of water, 26°C tap water, and a target water temperature of 8°C, that is 180 × 18 ÷ 106 ≈ 31g of ice and 149g of tap water. If the calculated water temperature is below 0°C, water alone isn't enough, so combine other measures such as chilling the flour in the fridge, lowering the room temperature, and shortening the mixing time.
- How many degrees does the dough warm up while kneading by hand or in a bread machine?
- Compared with the average of the room, flour, and water temperatures, dough usually rises 2–4°C with hand kneading and 5–8°C with a mixer or stand mixer. A bread machine varies a lot with the model and mixing time. Measure the center of the dough once after mixing and work out your own value with temperature rise = actual dough temperature − (room + flour + water temperature) ÷ 3, and you can match the temperature more accurately from then on.
- How do I reverse-calculate a baker's percentage formula from the final dough weight?
- Flour weight = final dough weight ÷ (total of the formula percentages ÷ 100). To make 450g of dough from a formula that totals 180%, the flour is 450 ÷ 1.8 = 250g, and every other ingredient is 250g × its percentage. Making 2–5% extra to allow for what is left on the bowl and bench keeps you from running short when dividing.
- How do I count the hydration of a dough with milk or eggs?
- Milk is about 88% water, whole egg about 75%, and butter about 16%. Adding that water to the water and dividing by the flour gives the effective hydration. With 100 flour, 35 water, 20 milk, 15 egg, and 15 butter, it is 35 + 17.6 + 11.25 + 2.4 = about 66%. If you compare only the water figure, recipes with a lot of milk or egg look stiffer than they are.
- How many grams of dough go into a 1-loaf pan?
- Dough weight for the pan = pan volume ÷ specific volume. For a 1-loaf pan of about 1,700 ml, that is about 450g for a Pullman loaf (specific volume 3.8) and about 400g for a peaked loaf (4.2). Pans differ in size by product, so measure the inside dimensions or fill the pan with water to measure its volume before calculating.
- How many grams of dry yeast equal a given amount of fresh yeast?
- A rough guide is fresh yeast 3 : active dry yeast (the kind that needs proofing) 1.5 : instant dry yeast 1. For a recipe with 9g of fresh yeast, that is 4.5g of active dry yeast or 3g of instant dry yeast (about 1 teaspoon). Some manufacturers specify instant as 0.4 times the fresh amount, so also check the product label.
